The Castle Peak 100k is arguably one of the most difficult trail races in the country. Masked by its spectacular beauty, this is a true mountain race unlike any other on the ultra-running circuit. A rare point-to-point course offering genuine support with fully stocked Aid Stations that is staffed by experienced ultra-running volunteers. The race starts near the historic Emigrant Trail in Truckee, California at the Stampede Reservoir boat launch before ascending (and descending) over 16,000′ at an average elevation of 7,300′ above sea level. The course travels over roughly 95% of demanding single-track trails while journeying through some of the most dramatic scenery and vistas the region has to offer.
The course will take you through the Tahoe National Forest, Tahoe Donner, and Euer Valley, prior to climbing Hawk’s Peak. Traversing along the Donner Lake Rim Trail you’ll enter the hidden beauty of the Warren Lake Loop. New for 2021 the course will have two new out and back sections. One descends to Frog lake and the other descends to Warren Lake. These two additions add the unique opportunity off visiting Frog Lake which has been private land for nearly 100 years and experiencing the 1,100 foot descent and return to Warren Lake. Dont be fooled these additions albeit it beautiful will challenge the most seasoned ultra runner.
Continueing on you will then head to Basin, Castle and Andesite Peaks. You’ll then enter the notorious Hole in the Ground trail, where time seems to stand still. Once you reach the other end of the trail you will have a 1.25 mile paved stretch of Donner Pass road to the finish line at Soda Springs Ski Resort
