We are very excited to present our longest race distance, the 100 mile endurance run. This will be an unforgettable single-loop trek completely circumnavigating the Pioneer Mountain Range of central Idaho. Runners can expect the following:

  • 12 fully stocked aid stations
  • custom belt buckle for finishers
  • experienced race staff and volunteers
  • technical t-shirt
  • a well-marked course
  • event communication and medical support
  • many hard ascents and high-altitude views
Emily Berriochoa, the very first finisher. 46:28:54 July 2021.

This is NOT an easy course. Three of the aid stations are completely hiked in. You must be in very good shape to run this event, and there will be many stretches of the course with very difficult access if you become hurt or lost. Listed below are resources for your logistics.

We have shortened the 100 mile race to eliminate some pavement and warm weather the evening of the 100 mile start. These changes have been updated in the resources below.
