I. Sign-up

Registration for the HURT 100 will take place on  Please read the instructions below for registration information.

This event is open to participants who are at least 18 years of age. Registration will open on July 30, 2024, and will close at midnight (HST) on August 11, 2024. All interested runners must complete the race application at

After the lottery is conducted on August 24, 2024, and runners are chosen, payment will be processed. Upon successful processing of the transaction, an applicant is deemed an entrant in the event. If payment cannot be processed for any reason, the applicant has seven days to resolve the problem; after that period, the applicant is replaced by the first waitlisted runner and moved to the end of the waitlist.

II. Entry Fee

The entry fee for the HURT100 2025 is $355, plus 4.712% Hawaii General Excise Tax ($371.73 total). HURT has moved to its own payment processor, eliminating additional registration fees.

III. Trail Work Requirement

Entry to the 2025 HURT 100 will require eight hours of volunteer trail work.  Volunteering at an ultrarunning event, or pacing/crewing during an event, DOES NOT fulfill the trail work requirement.  Trail work for the 2025 HURT 100 must be completed between November 16, 2023, and November 15, 2024.  Full details of the requirement are on the Trail Work form, found on 

  • We will update the roster on to show acceptance of your Trail Work form.  If you have submitted a Trail Work form and the website is not updated within 3 days, contact us at
  • Entrants not submitting verified Trail Work forms to by the deadline of November 15thwill be removed from the event.  Refunds for removed runners will be in keeping with the Refund section below. 
  • NEW: Waitlisted applicants have the same November 15th deadline for submission of Trail Work forms. After the November 15th deadline, waitlisted applicants who have not submitted their Trail Work form will be removed from the waitlist. (They will still be considered waitlisted for future lotteries.)
  • All entrants are encouraged to complete their trail work as soon as possible. 
  • Questions concerning the Trail Work requirement may be sent to

IV. Qualifying Event

To make sure that entrants have enough experience to attempt our grueling 100-mile race, HURT has implemented a requirement of a qualifying run of a minimum of 50 miles.  Any official run of 50 miles or longer, with publicly available results that meets the criteria below, is acceptable. 

  • You must finish the run within the official cutoff times for that event. Completing 50 miles of a longer event that you did not finish will not be accepted. 
  • Completing 50 miles or more as part of an official, timed running event, such as a 12-hour, 24-hour, Backyard, or similar event, when the distance is publicly available in the results, is acceptable.
  • Virtual events, FKTs, stage races (unless a single recorded stage is over 50 miles), and events created solely for the purpose of producing a qualifying run will not be accepted. Due to their inherent informal nature, Fat Ass runs will also not be accepted.
  • The run must have been completed within the two years prior to the opening of registration, from July 31, 2022, to July 30, 2024.  It is the responsibility of the applicant to list their qualifying run at the time of application, along with a web link to where the results can be found. 

V. Runner Selection – HURT 100

As we continue to grow in popularity, HURT has adapted our selection process to provide the greatest opportunity for the ultimate ultrarunning experience.  To meet the needs of our HURT veterans, those waitlisted from previous HURT events, newcomers to HURT, and our State and County partners, we have developed the following selection process for entry into the HURT 100.

The HURT 100 will have three lottery categories, determined automatically based on HURT historical records:

  1. HURT Veterans – up to 18 slots will be allocated to this lottery, which is for anyone who has three or more HURT 100 finishes. 
  2. Waitlisted but Never Selected – up to 40 slots will be allocated to this lottery, which is for those who have applied in the past but have never been selected to run in the HURT 100.
  3. Everyone Else – up to 60 slots will be allocated to this lottery, which is for everyone not in the previous two categories of lottery. This includes first-time applicants to the HURT 100 and those who have been selected for the race in the past. “Selected for the race” includes:
    1. Entrants who finished HURT one or two times.
    2. Entrants who have a recorded Did Not Finish (DNF) or Did Not Start (DNS).
    3. Entrants who withdrew their entry after paying or did not respond to the invitation).

The initial entrant list will include 140 runners, including the reserved slots listed below. HURT has a goal of starting 135 runners (or the current permitted limit at the time of the event).  HURT has developed the following selection process for the initial 140 entrants, to reflect the goal of making the selection process more transparent to all.

VI. Reserved Slots

HURT has reserved up to 22 of the 140 slots for HURT use:

  1. HURT immediate previous year (2024) top 3 finishers in each division (men, women, non-binary): Up to nine slots.
  2. HURT Board Discretion: Ten slots.  HURT can use this at any time, for any reason that HURT feels can add to the event.
  3. Peacock Challenge 55:  Up to three slots (one man, one woman, one non-binary) to Peacock Challenge finishers who are also on the HURT 100 waitlist.
  4. Any slots not awarded will be used as additional draws from the waitlists.
HURT Board Discretion10Any time
Previous year top 3 in each division9Any time
Peacock Challenge 553After the Peacock Challenge in October
TOTALSUp to 22 

All runners selected in the above categories must have entered HURT and fulfilled all the entry requirements for the HURT 100.  Selected runners will be notified by email with an invitation to participate and information on making payment. The recipient has seven days to accept and submit payment to become an entrant. 

VII. Lottery Process

After the HURT-reserved 22 slots, 118 slots remain OPEN for the lottery.  HURT will select the following number of applicants from each pool.  The selection process will be by separate lottery for each pool.

HURT Veterans18First Pull
Waitlisted but Never Selected40Second Pull
Everyone Else60Third Pull

VIII. Kukui Nut Assignment Process

The HURT 100 conducts a weighted lottery.  Each entrant will receive kukui nuts, which are “tickets” in the lottery drawing. Each kukui nut increases an entrant’s odds of being selected.  Kukui nuts are awarded as follows:

  • All applicants will receive:
    • One kukui nut for applying.
    • One kukui nut for each HURT 100 finish in the five previous years.
    • One kukui nut if they have any finishes more than five years ago.
    • One kukui nut for Hawaiʻi residents.
    • One kukui nut for being an official volunteer at  the 2024 HURT 100 and utilizing the HURT 100 volunteer platform, SignUp Genius.
  • Applicants in the Everyone Else category will receive one kukui nut for each year on the waitlist they were not selected within the last three years.
  • Applicants in the Waitlisted but Never Selected category will receive two kukui nuts for each year on the waitlist within the last three years.

IX. Conduct of the Lottery

Board members will tabulate the number of kukui nuts allotted to each entrant, based on HURT’s historical data and the data provided by the entrant during registration.  All data are verified through records maintained by the HURT 100.  The number of kukui nuts for each entrant will be posted on the HURT website the week before the lottery.  All applicants should review their number of kukui nuts and selected lottery category for accuracy and follow instructions on the website if they think there is an error. 

Following the lottery, selected runners will be sent an invoice for payment and the website roster will be updated. Runners will have seven days to complete payment, at which time they are officially accepted into the HURT 100. If payment is not received after seven days, the selected runner will be removed.  To ensure that notification is received, all registrants are asked to set their email spam filters to accept correspondence from,, and email addresses.

The lottery will be conducted on August 24, 2024.  Information regarding live streaming of the lottery will be published prior to that date.

X. Waitlist

A separate Waitlist will be maintained for the following lottery categories:

  1. HURT Veterans
  2. Waitlisted but Never Selected
  3. Everyone Else

After entrants are selected in all three lottery categories, the random drawing from the pool of weighted applications will continue, in order to create a waitlist for each category.  A maximum of 50 names will be drawn for each category, ranked by the order in which they are drawn. The three waitlists will be posted approximately three days after the lottery on HURT100.comNames not drawn are still considered “waitlisted” for future lotteries, and further names will be drawn if the initial list is exhausted.

When a runner withdraws from the start list, a runner will be taken from the waitlist for the lottery category for which that runner was chosen.  If a waitlist is empty, runners will be selected from the other two categories on an alternating basis, beginning with the “Everyone Else” list. 

If an entry slot becomes available, the first runner on that waitlist will be notified by email with an invitation to participate. The recipient will also receive an invoice for online payment of the race entry fee and will have seven days to accept and pay. If the recipient declines, or no reply is received, the invitation will be revoked, and the next available waitlisted runner will be notified.

The waitlists will be posted on together with the list of entrants from each lottery category. These lists are updated daily when new information is received. All waitlisted runners should monitor their progress as waitlisted runners are offered a spot in the race.  Most turnover occurs in the immediate week or two after the lottery and after the November 15 refund deadline.  No invitations to register will be issued to waitlisted applicants after December 31, 2024. 

XI. Withdrawal

Runners should immediately notify the Director of Race Admission of a decision to withdraw from the event. Admitted runners who fail to show up on race day without notifying the Director of Race Admission will be banned from entering the HURT 100 for the next three years.

XII. Transfers / Deferment

Accepted or waitlisted runners cannot transfer entries to other individuals. Entries and entry fees cannot be deferred or rolled over to a future year.

XIII. Cancellation of Event

This event is held on public land, under the management of the Department of Land and Natural Resources.  As a result, the race directorate does not have the final say as to whether the event will be held, or the course altered. In the event of an emergency cancellation, no refunds will be given.

XIV. Refunds

HURT 100 runners are eligible for a refund of 50% of registration fees, if both of the following conditions are met on or before 11/15/2024: a notice of intent to withdraw from the event is sent to the Director of Race Admission and a waitlisted runner accepts the vacated spot. After 11/15/2024, entry fees will not be refunded for any reason and under any circumstances.


I. Introduction

The HURT Trail 100-Mile Endurance Run, referred to hereafter as the “HURT 100”, is a very difficult event designed for the adventurous and well prepared ultrarunner. It is conducted on trails within the jurisdiction of the State of Hawaiʻi Department of Land and Natural Resources (DLNR), Division of Forestry and Wildlife, Nā Ala Hele program. Nā Ala Hele has turned traces of pig trails through the rain forest into people-friendly, single-track paths. The event organizers are very grateful for the staff’s untiring year-round commitment to trail maintenance for all users and help in preparing for this annual event.

A detailed description of the course can be found at the end of this document.

  • Temperature
    • Average Maximum for Honolulu in January – 80.0° Fahrenheit
    • Average Minimum for Honolulu in January – 65.8° Fahrenheit
    • Extreme Daily High for Honolulu in January – 88.0° Fahrenheit
    • Extreme Daily Low for Honolulu in January – 52.0° Fahrenheit
  • Precipitation
    • Monthly Mean for Honolulu in January – 3.34 inches
    • One-Day Maximum for Honolulu in January – 6.40 inches
  • These measurements were gathered from a weather station at the Honolulu airport (HNL), and do not apply with precision to the rain forest. Participants should expect lower daytime highs and nighttime lows, especially on the exposed sections of Mānoa Cliff and Nu‘uanu ridge. Precipitation is higher in the rain forest than in the urban areas of Honolulu and can fall in huge quantities over a brief span of time. Regardless of rain, high relative humidity should be expected.
  • All times are expressed in 24-hour format, pertaining to race weekend, and are listed in order of occurrence; dusk and dawn refer to “civil twilight” (sun six degrees below horizon).  Times listed are for January 18, 2025.
    • Dawn – 06:47
    • Sunrise – 07:11
    • Sunset – 18:12
    • Dusk – 18:36
    • Moonrise – 22:46  (Moon phase: waning gibbous, 79.1% illumination )
    • Moonset – 10:56 (Jan. 19)
  • The dense canopy covering much of the course leads to effectively shorter daylight hours. Even in years with nearly a full moon, the moon will not provide much illumination through the canopy. For the HURT 100 in 2025, moonrise will be four hours after dusk. Even with moon illumination at 79%, participants should anticipate needing artificial light for longer than indicated by the times listed above.
Altitude / Elevation Change
  • Over the 100-mile course, the elevation ranges from 300 to 1900 feet. The total cumulative elevation gain is roughly 24,500 feet. For the technically inclined, the GPS sampling interval for this calculation was about 100 meters.
  • The HURT 100 course consists almost exclusively of technical, single-track trail on surfaces that include roots, rocks, and soil in a wide range of conditions, from sun-baked clay to mud of varying depth. Sudden hairpin turns and steep inclines of up to approximately two miles in length are a common occurrence. Very few sections of the course can be run with a consistent stride for more than several hundred yards at a time.
  • There are a total of 20 stream crossings. Mānoa Stream and Nu‘uanu Stream are each crossed twice per lap at locations close to the Mānoa and Nu‘uanu Aid Stations, respectively.
  • Wild pigs roam the trails and are most active at sunrise and sunset. Although they tend to avoid humans, they are temperamental and have dangerous tusks. When encountering a pig, especially a sow with piglets, trail users should avoid sudden or aggressive movements.
  • Mosquitoes can be present in the wetter areas of the course alongside stream crossings and at some aid stations, especially when there is little air movement. Participants may want to pack appropriate clothing and/or repellant.
  • Bacteria (including leptospirosis) are prevalent in freshwater streams and ponds found in Hawai‘i. Please do not drink stream or pond water. As aid stations are close, runners should not need to use streams as a hydration source. Runners should also note that leptospirosis can enter the bloodstream through any open wound. 

II. Race Logistics

The Course
Course Markings
Aid Stations
  • There are three aid stations spaced from 5.2 to 7.4 miles apart: Makiki (the Start / Finish, located at the Hawai‘i Nature Center), Mānoa (located at Paradise Park), and Nu‘uanu (located at Judd Trail trailhead). All aid stations will be stocked with bottled water, an electrolyte drink, and carbonated beverages. Hot and cold food will be available, with vegetarian and vegan options in each category. Food items will include the traditional fare that is provided at most 100-mile runs, as well as local variations of the standard theme.  While the aid stations are well stocked, there are certain items that will not be available:  runners are responsible for their own gels, energy bars, electrolyte supplements, medications (e.g., anti-inflammatory products), personal hygiene products (e.g., sunscreen, lip balm), and typical first-aid items (e.g., bandages, blister treatment). Those with strict dietary requirements or special medical conditions are advised to pack needed items in personal drop bags.
  • REMINDER: The HURT 100 is a cupless race.  (Exceptions are made for hot beverages and for volunteers.) 
Drop Bags
  • Runners may have personal supplies at any of the three aid stations. Each aid station will be visited five times, so attention to resource planning is important. Due to space limitations and to facilitate handling, the size of drop bags is limited to 12 inches by 12 inches by 18 inches, as detailed in Rules.
  • As aid stations close, race personnel will transfer drop bags from the peripheral aid stations (Mānoa, Nu‘uanu) back to the Hālau Kū Māna parking lot at 2101 Makiki Heights Drive (at the bottom of the road leading up to the Makiki Aid Station). Participants are responsible for gathering their drop bags following the event by 18:15 on Sunday, January 19. Any items not collected by then will be donated, recycled, or discarded.
  • Drop bags will only be delivered back after the closing of each aid station, to the Hālau Kū Māna parking at Makiki. If you finish or drop early, you’re welcome to retrieve your bag from each individual aid station, to save you time waiting for final aid station closure. Please let the aid station volunteers know you are taking your bag. Runners or crews picking up bags at Nu‘uanu may not park or stay at the aid station. Please just grab and go.
Pacers / Crews
  • The HURT 100 is a competitive race for some, a running event for others, but an independent challenge and personal test of fortitude for all. A pacer is a safety companion during the latter part of the event only, not a way to gain advantage over fellow runners. A similar sentiment applies to crews, which are also considered nonessential as ample and regular support is provided by aid-station personnel. Runners need to be able to carry necessary supplies and maintain forward progress independently, from start to finish. Note: The ultrarunning community in Hawai‘i is relatively small, and pacers may be hard to find locally. Runners are responsible for the conduct of their pacers, regardless of how they are acquired.
  • Awards (belt buckles) for all 100-mile finishers will be given immediately at the time of race completion. 
  • We Wouldn’t Want It To Be Easy Award: This award is in honor of Big John Salmonson. John provided much support and mentorship to everyone who crossed paths with him, and he took great pride in helping to create and grow one of the hardest events in the country, the HURT 100. John always felt that overcoming significant obstacles, going deep into discomfort, and coming out the other side with a finisherʻs buckle was the recipe for transforming an athlete into the best version of themself. This award honors a finishing runner who overcame challenges and conquered the HURT 100 and, as a result, grew as an athlete and human.
  • Selected finishers will be awarded a custom-made, custom-fitted HURT belt to complement their new buckle. Recipients will be announced at the HURT banquet.
  • The first three finishers in the men, women, and non-binary divisions will receive event-specific trophies at a ceremony during the Post-Race Banquet. Runners unable to attend the banquet should note that awards will not be mailed and must be collected locally.
  • A prize of $500.00 will be given for any new course record established for each division in the HURT 100. The current records are 19:35 (men) and 24:06 (women).
  • Makiki: Parking at the Makiki Aid Station (Start / Finish) is limited; carpooling and arranging rides are recommended. One parking pass will be issued to each runner, for one vehicle to park at Hālau Kū Māna, which must always be displayed.  Runners and crews should use the lower parking lot before the gate.  We will once again try to obtain parking at the adjacent  Hālau Kū Māna School, but this may not be confirmed until just prior to the race.  Participants may also park along Makiki Heights Drive but must have all tires off the roadway or risk being towed. Runner or crew vehicles are NOT permitted above the gate. The DLNR has advised race planners that only necessary traffic will be allowed to pass through the front gate after hours (typically sunset to sunrise), as the park needs to be secured. On race morning prior to the start, a parking attendant will direct drivers. 
    • Note: There are several private homes along the roadway leading to the Makiki Aid Station. Travel and noise (e.g., conversations, closing of car doors and trunks) should be kept to the absolute minimum, especially during nighttime and early morning hours. There is no parking above the gate by runners or crews.
  • Mānoa: The Mānoa aid station is located on the Paradise Park grounds. Paradise Park, including the parking lot, are private property. A $7 parking fee (subject to change) applies for the duration of the event. Free street parking is available around the end of Mānoa Road, 5 − 10 minutes by foot from the aid station.  If parking on Mānoa Road, do not block neighborhood driveways. Due to traffic and parking congestion on the first loop, no crews are permitted at this aid station until after 10:45 a.m. on Saturday.
  • Nuʻuanu: There is no access to the Nuʻuanu aid station.  Nuʻuanu Pali Drive is a narrow road adjacent to the aid station that offers extremely limited parking. PACERS MAY NOT start at Nuʻuanu.  Pacers or crews showing up at Nuʻuanu could result in runner disqualification. Due to limited parking, we will use a shuttle for volunteers.
  • All Locations: Trailheads are notorious for vehicle break-ins. Participants are strongly encouraged to avoid leaving valuables in their cars. Note that vehicles must have all four wheels off the road (asphalt surface) to avoid ticketing or towing by the police.
Race Photography
  • Race Management provides two or three approved volunteer professional photographers for this event. These photographers can be identified by yellow photographer vests. Post-event, these photographers may offer photos for purchase. Runners should note that these photographers take thousands of photos during the event, and it takes some time to process them and make the race photos available.
  • The best places to see a runner and capture photographs are near aid stations. Those who venture onto the course are asked to exercise caution and respect the environment, runners, and other trail users. Many spectators who take pictures share them through the HURT 100 website (use the contact form on our website to have photos posted).

III. Safety / Medical Concerns

Participants have voluntarily entered an event which requires a significant amount of mental and physical preparation. In addition, the race involves inherent risks ranging from the known (e.g., terrain, 100-mile course) to the unknown (e.g., “acts of God”). Runners and pacers should ensure adequate medical coverage in the event of mishap during this event.

Medical Personnel

Although event personnel will make all efforts to provide aid within their capabilities, medical staff may not be available to take care of participants. Each aid station is located within a 5-mile radius of a major medical center.

Cell Phone Coverage

Cell phone service is available on parts of the course but can range erratically from adequate coverage to none at all. Quality and reception will also vary among cellular phone carriers. Carrying a whistle is recommended for both runners and pacers.


If a runner gets hurt on the trail, they should stay put, keep warm, and remember that this is a multiple-lap, out and back course. Other runners or the HURT Patrol will direct event personnel to the incident location or assist in another manner. Similarly, if a runner gets lost, they should stay on the trail and wait for assistance. Wandering aimlessly, especially at night, reduces the chance of being found.

An emergency telephone number will be printed on your race bibs. This number will connect to race personnel and should only be used during the race, if injured or lost.


One of the most common medical problems for endurance athletes is dehydration. This is especially relevant for the HURT 100 as conditions on the course can be hot and humid. Runners are solely responsible for monitoring their own hydration levelrace officials will not be weighing participants. Runners should leave each aid station with a minimum of 32 ounces of water, with 64 ounces being highly recommended.


Hypothermia may pose a threat at night, especially if it has rained, as temperatures can drop below 60 degrees Fahrenheit. Sections of the course along ridges and cliffs, including Mānoa Cliff Trail and Nu‘uanu Trail, are extremely exposed and can be very windy and wet.

Road Crossings

On each lap, runners must make two road crossings. One of them involves following a narrow road for approximately 150 yards. Runners must use extreme caution when running across or along roadways. Crossing roads safely is solely the responsibility of the runner.


Participants will be running on technical trails where footing is adequate at best. If it rains, which is common, there can be an abundance of mud. Attention to the terrain underfoot and directly ahead is critical in this event. Some trails are located adjacent to cliffs with extreme drop-offs.

There are two major streams, and each is crossed twice per loop. One major crossing is short and non-technical, involving wood planks not far from the Mānoa Aid Station. The other is technical and requires runners to cross Nu‘uanu Stream on scattered and slippery rocks, near the Nu‘uanu Aid Station. Runners  will likely get wet feet when crossing this stream. If the water level is high, the course may be rerouted. Runners will be notified of any course changes at the Pre-Race Briefing.  Depending on recent rainfall, parts of the trail will be quite muddy and/or cross minor run-off streams.


As no part of the course (except for the aid stations) is lit, and very little moonlight penetrates the forest canopy, race participants will need artificial light at night. Runners (and pacers) are reminded that daylight hours are shorter in the forest than in the open. Participants should carry backup batteries and lights and keep extras in drop bags. Aid stations are not stocked with batteries for runners to use.

Hiking Poles

Poles are permitted on the course. For safety reasons, those with poles should yield the trail to other runners.


Use of any device that impairs the senses is discouraged for safety reasons. Runners wearing headphones are asked to remove them when near aid stations to facilitate communication with event personnel.


Use of bells and other devices emitting sound is prohibited out of respect for other trail users seeking a wilderness experience.


I. Introduction

HURT 100 Rules are designed with the following goals in mind:

  • The safety, enjoyment, and well-being of everyone involved in the race, including runners, pacers, crews, volunteers, neighbors, race personnel, spectators, and others using the trails (“the public”).
  • The staging of a fair and sportsmanlike event that is solely based upon individual effort.

Failure to comply with these rules or failure to promote the goals above may result in disqualification of a Runner. Depending upon severity of the offense, Runner can be disqualified for this race and future HURT sponsored events. Additionally, the race directorate may refine, generate, or reinterpret a rule at any time if doing so is deemed necessary to promote our goals. At all times, the intent and spirit of the rules will govern how they are implemented and enforced by race officials (e.g., Race Directorate, HURT Patrol, Aid Station Captains). By attending this event as Runner, Pacer, or Crew, each participant acknowledges and agrees with this sentiment.

II. All Participants

  1. Courteous behavior and sportsmanlike conduct are always expected.
  2. Sharing the trail: HURT 100 participants do not have exclusive use of the trails.  These paths are well used by the public.  Caution should be exercised when approaching casual hikers (and their pets).  Runners should warn others of their approach and, when in doubt, yield.
  3. Use common sense when passing other trail users or runners. Yield to other trail users if it is safer for you to stop or pull off the trail to the side.
  4. If you see a struggling runner, ask if they need help. Report at the next aid station or help them call for assistance, if necessary.
  5. HURT 100 participants do not have exclusive use of public toilets or drinking fountains at the Makiki Aid Station. These should be used with care, keeping in mind that they are shared with hikers and the public.
  6. Mālama ʻāina (care for the land).
    • The rain forest is fragile and subject to damage simply by being trod upon. Runners and pacers are expected to stay on the trail at all times.
    • Littering on the course is grounds for immediate disqualification. Littering is contrary to land use ethics and affects HURT’s ability to hold future events. Note: Dropping waste anywhere on the ground outside any aid station is considered littering.
    • The HURT 100 course lies within watershed areas that supply a significant amount of potable water for residents of Oʻahu. Participants should use the restrooms available at Makiki (Start / Finish), and the portable toilets at all aid stations.
    • If unable to wait for an aid station portable toilet, follow the “leave no trace” requirements: Move at least six feet off the trail. Use a trowel, stick, rock or shoe heel to make a hole about 4 inches wide and 6 to 8 inches deep. If the ground is too hard or rocky to dig, try lifting a rock and use that spot. Replace the rock when you’re done. Or carry your waste out in a bag.
  7. Muling is not permitted. Runners must carry all of their supplies into, out of, and between aid stations, at all times.
  8. Runner’s lighting system is to be used for personal illumination of the trail only. Pacer may not deploy lighting systems to illuminate the trail for Runner except temporarily in case of an emergency.
  9. Short roping of Runner, by tether or connected body parts, is not permitted. Runners must complete the course under their own power without being pulled, pushed, balanced, towed, carried, supported, or physically guided over the course.
  10. Stashing of supplies is not permitted at any time or place on the course. This includes leaving water bottles on out and back sections of the course, even during the event itself (a form of littering).  Stashing supplies is considered littering and is grounds for immediate disqualification.
  11. Aid from Crew or Pacer may ONLY be given at official aid stations.

      • Nuʻuanu,
      • Makiki (i.e., Start / Finish)
  1. Runner bib numbers must be worn on the front of your clothing and NOT be folded.  This is to ensure they are visible and that runners are properly identified at aid stations.
  2. While accepting supplies on rare occasions from another runner is tolerated, multiple such instances may be interpreted as muling.
  3. No course cutting. Runner must follow the marked course at all times. If Runner departs from the official course, Runner must return to the point of departure on foot before continuing onward.

  9. Runner exceeding one hour in an aid station must report it to the aid station captain.
  10. Runners dropping out during the event must inform a race official. If Runner retires without doing so and fails to show up at the next aid station, race officials may notify Honolulu Fire Department Search and Rescue (SAR).

Race staff will make every attempt to shuttle Runner back to the Start / Finish (Makiki) if this occurs. Note: The official race time clock is managed by race timers and corresponds to satellite time.
  12. The short boardwalk at Pauoa Flats (Roots) is not to be used by the Runner on any loop, and this area will be marked with blue tape. This boardwalk can become very slippery and hazardous.

III. Role Definitions

HURT Patrol

Patrols will be on the course to monitor the progress of runners, assist during emergency situations, assess course conditions, refresh course markings, and prevent / report rules violations. Members of the HURT Patrol serve as extensions of the race directorate. As such, they are authorized to warn runners, pacers, and crews of any violations and advise them to correct transgressions.

The HURT Patrol will be on the course and at aid stations throughout the event.  They may provide directions, help with medical needs, and provide race-related assistance.  They may not provide aid, such as water, energy bars, gels, ibuprofen, batteries, headlamps, etc. In the event of a serious injury, the HURT Patrol will follow race emergency procedures to ensure that the person is properly taken care of and will remain with them until attended to. The Patrol will also assist the Race Directorate to see that all are following the rules and are respecting the ‘aina. 

Aid Station Captain

Aid Station Captains plan and organize aid stations, as well as supervise their setup and disassembly. During the event, they direct volunteers and oversee operations related to runner support and safety. Aid Station Captains serve as an extension of the race directorate.

The briefing will include distribution of information including logistics / course updates, safety, and other topics, as well as a question and answer session. In addition, runner bags will be distributed at the meeting. 

Mandatory Runner Check-in

Runners need to check in prior to the start of the race in order to receive the runner bib and be officially recognized. Times will only be kept for official runners.

Drop Bag Collection

The official and only occasion that drop bags are collected for distribution to the Mānoa and Nuʻuanu aid stations occurs at the Makiki aid station immediately after Runner Check-in.

Post-Race Banquet

We are looking forward to another fun filled evening of race awards, roasting of runners, and mingling with friends old and new. HURT will publish banquet and ticket information as plans are confirmed. Once plans are announced, early purchase is strongly recommended as we tend to quickly fill to capacity.


Runners are allotted 36 hours to finish the 100-mile event, from 06:00 on Saturday, January 13 to 18:00 on Sunday, January 14. Cut-off times pertain to the fifth lap (Miles 80-100). Runners must check out of each aid station by the time listed in the chart below or drop out of the race. Checked-out runners returning to aid stations after the listed times must exit the race or face disqualification. Aid stations close fifteen minutes after the cut-off.

The cutoff times above apply to ALL runners, regardless of their mileage covered.

The Race Director, aid station captains, or medical staff may pull a runner at any point if, at their sole discretion, the runner’s safety is deemed to be at risk on the way to the next drop point. Additionally, the Race Director or aid station captains may pull a runner (who is not on loop 5) at any point if, at their sole discretion, they deem the runner unable to make the next drop point prior to it closing.


The HURT 100 course consists of five identical 20-mile laps on trails connecting the Mānoa, Makiki, and Nuʻuanu valleys. A leg of this lap is defined as the connection between any two aid stations.

The route is marked with directional signs and surveyor’s tape in three different colors (white, lime green, and orange), one for each of the three legs. On out-and-back sections of the course, runners will encounter ribbons in two different colors. Blue tape indicates shortcuts and trails that are not part of the course. At night, glow sticks may be placed at critical turns.

A brief description of the ordered sequence of trails that make up the HURT 100 course is given in the following table; prominent natural or man-made landmarks are mentioned as well.

Note: At any time, the course may be altered at the race directorate’s discretion. Should that be necessary, the race directorate will email instructions and course information as early as possible to assist runner preparation.
