Burney Mountain 100
The Burney Mountain 100 is a 100 mile mountain trail race scheduled for June 18, 2027, in Cassel, California, organized by Intermountain Endurance. The event is a single loop that begins and finishes at Burney Mountain Guest Ranch and runs through Lassen National Forest, the Burney Basin, and the Thousand Lakes Wilderness.
The course has four possible variations labeled A, B, C, and D that adjust upper elevation sections based on seasonal snowmelt. Course A is the only route that fully summits Magee Peak and is used in low snow years. Regardless of variation, the course is remote and includes a mix of rocky ridgelines, soft forest floor, high country slopes, and singletrack.
The route includes roughly 15,000 feet of cumulative climbing and offers views of Mount Lassen, Mount Shasta, the Hat Creek Rim, and regional volcanic landscapes. Runners are required to carry the course GPX file on a watch or phone as provided in the race materials.
Beginning in 2027, participants must complete either 8 hours of trail work or 12 hours of race volunteer service; full submission instructions and deadlines are provided in the Runner's Guide. The Runner's Guide also contains aid station, drop bag, crew, and pacer information. The event follows a cup less policy; runners should bring a reusable cup.
Burney Mountain Guest Ranch provides free dry camping for runners and crew on Thursday, Friday, and Saturday nights and offers lodging upgrade options with a $25 discount for runners. Amenities at the ranch include a restaurant, saltwater pool, laundry, and cornhole. Nearby attractions include Burney Falls, Lassen National Park, and other regional sites.
