The Castle Peak 100k is presented by and produced by the Donner Party Mountain Runners, a grassroots non-profit running club. Our mission is to inform and inspire mountain runners in Truckee-Tahoe. We hope this challenging, scenic, and historic course will inspire you to explore new frontiers.
The Castle Peak 100k is dedicated to the spirit of those early emigrants to California, including the Donner Party, who were “Facing the brunt of fate. Indomitable. Unafraid.”
