River of No Return Endurance Runs
June 15th 2024

Designed to be tough and beautiful, the courses tour some big mountain climbs over 9000 feet. Elk, deer, eagles, bears and wolves add to the mystique of the River of No Return, as do the forgotten mines and mining communities, old Idaho traditions – all surrounded by the very supportive community of Challis. 

Runners will be treated to a fast finish down Main Street Challis and back to the Challis City Park. Enjoy the return to civilization in the last mile as the locals cheer you home!
