Pierres Hole, once known for fur trade in the Northern Rockies, has always been a test of endurance, fortitude, and strength. For almost two decades, the Pierres Hole 50/100 has provided an incredible experience to everyone who has raced in this epic journey. The racecourse views are breathtaking, the singletrack is better than ever, and you will be tested by the rugged terrain that makes riding on the west side of the Teton Range so spectacular. The entire race is held at Grand Targhee Resort, where ample lodging and amenities await racers and their families.

Numerous classes in both 50k and 100k distances are available! Sweet swag bag for all participants and cash prize for podium finishers.
