The Castle Peak 100K

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 Truckee/Tahoe locals and experienced ultra-running volunteers. The race starts near the historic Emigrant Trail in Truckee, California at the Prosser Ranch Group Campground before ascending over 15,000' 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.
