HURT100 Course Map

Multiple formats are available as discussed below.  However, remember that all these maps are for general reference only. The errors in GPS measurements in the map and from your device in the mountains are often larger than the distance to a cliff edge or other hazard. Thus, while very useful to ensure you still on the race route and going in the right direction, you must constantly look out for trail hazards.

Geo-referenced PDF

  • This is recommended for those not very familiar with the course.
  • Detailed directions below.
  • While it takes a few minutes to set up with a free app with your smart phone, using these will allow you to see your current location in relation to the course map in real-time.  If set up ahead of time, this functionality is available while offline or in airplane mode (to save battery).

Maps from Book of HURT

  • We recommend you print out the maps from the Book of HURT and carry them with you.


  • This format is for those who desire a GPX file for their smartwatches.
  • Click here for the GPX file for a single 20 mile loop of the HURT100 course.

KML – Google Earth

  • These files are used if you want to view the course in 3D via Google Earth
  • Click here for the The HURT100 KML file.
  • To view in Google Earth, first download the file linked above.  Then within Google Earth, load the map by selecting Projects, then New Project, and then select the downloaded KML file.  Under Map Style you may need to set Turn on 3D buildings to OFF to see the entire trail unobscured by the tree coverage.

Google maps

  • Click here to show the course in Google maps. 
  • However, this will not be available offline and cell coverage along the course is spotty so we do not recommend relying on this while on the course.

How to download HURT race maps to your phone (Geo-referenced PDFs)

1. Install the Avenza app to your smartphone.

Download the free Avenza Maps app from these app stores

2) These maps also work in Gaia GPS or other apps if you have another favorite 

2. Download map into Avenza Maps app.

  • Open the app and create a free account if required
  • Tap on the plus [+] icon in the top right side of screen
  • Select “Import Maps”
  • Select “From the Web” and then type or copy/paste the website address and tap “go”
    • https://hurt100.com/HURT100-map.pdf

Important notes:

  • After you have followed these steps and see the map in the Avenza Maps app on your phone, on race day (or anytime you are actually on the map) you will be able to see your real-time location by simply opening the map.  The GPS location arrow in the bottom left will center the map on your current location.
  • It only requires GPS (not cell coverage) and will work in airplane mode if you are trying to save battery.
  • For those that want to see it working prior to race day:
    • If you are not on the course, you will not see your location.  If you want to have a map where you will see your real-time location (i.e. the blue dot) to get a feel for the app, you can use this map of all of Oahu:  https://caltopo.com/p/F08HC  Download this map using the same instructions above and as long as you are on Oahu, you will see where you are.
