Burney Mountain 100
The Burney Mountain 100 is a 100 Miler held in Cassel, CA that starts and finishes at Burney Mountain Guest Ranch and runs as a single loop through Lassen National Forest, the Burney Basin, and the Thousand Lakes Wilderness.
The final route varies with seasonal snow conditions. Organizers publish four possible course variations labeled A, B, C, and D. Course A is the only version that fully summits Magee Peak and is used in low snow years; Courses B, C, and D adjust upper elevation sections when snow limits access. Each variation retains a remote, high country character.
The course includes approximately 15,000 feet of cumulative climbing and a mix of terrain: rocky ridgelines, forest singletrack, soft forest floor, and open high country slopes. Scenic views along the route include Mount Lassen, Mount Shasta, and the Hat Creek Rim.
Beginning in 2027 all entrants must complete either 8 hours of trail work or 12 hours of race volunteer service; full details and deadlines appear in the Runner's Guide. Runners must download the GPX file to a watch or phone and consult the Runner's Guide for aid station, drop bag, crew, and pacer information. All Intermountain Endurance races are cup less; runners should plan to use a reusable cup.
Runners and crew receive free dry camping on Thursday, Friday, and Saturday nights at the guest ranch; lodging upgrades are available with a stated $25 discount for runners. Ranch amenities include a restaurant, saltwater pool, laundry, and cornhole. Nearby features include Burney Falls, Lava Tunnel, Lassen National Park, Chalk Cave, Hat Creek, Pit River, Baum Lake, and Lake Britton.
Race entries are non refundable. Deferrals are allowed up to one week before race day and transfers are permitted up to one day before race start. Visit the organization's website for the most recent information.
