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.
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 before summiting Basin, Castle & Andesite Peaks. You'll then enter the notorious Hole in the Ground trail, exiting into the famous Royal Gorge Cross Country Resort, then ascending and running along Razorback Ridge. Enter the infamous Palisades!* By way of Crow's Nest, this 1.25 mile section of scrambling, requires true grit. After your test of courage, you'll arrive at the summit of Mt. Lincoln and Judah, before your final descent into the finish at Sugar Bowl Resort. Click here to view all the details on the Castle Peak 100k website.

Castle Peak 100k is produced by the Donner Party Mountain Runners, an all-volunteer non-profit organization. Thank you for supporting our mission to inform, inspire, and connect mountain runners in Truckee-Tahoe. We will be communicating course preview options throughout the summer.
***ALL RUNNERS MUST ACKNOWLEDGE THE FOLLOWING***
Devil's Oven (Mile 33.5): Due to the remoteness of the Devil’s Oven Aid Station (Mile 33.5), there will be VERY LIMITED WATER and fuel options at that location. Participants will need to fill up on supplies at the Johnson Canyon (Mile 24.5) and Summit Lake (Mile 28.2) Aid Stations.
Palisades (Mile 57): The 1.25-mile Palisades section includes very technical, risky & exposed scrambling. This may not be appropriate for those with a fear of heights. The Palisades section will be staffed with safety volunteers at key sections, in addition to guide ropes to assist participants through this segment of the course. Passing or over-taking within the Palisades will only be allowed during daylight, and only at locations specified by safety personnel. LED lights will be attached to course markings for all sections of the course that may be travelled in the dark.
