Burney Mountain 100
The Burney Mountain 100 is a 100 mile loop race in Cassel, CA that travels through Lassen National Forest, the Burney Basin, and the Thousand Lakes Wilderness. The route starts and finishes at Burney Mountain Guest Ranch and passes volcanic peaks, dense forest, high‑country slopes, and remote singletrack. The course includes roughly 15,000 feet of cumulative climbing.
Because the race crosses high mountain terrain, organizers use four course variations (Course A, B, C, and D) that adjust upper elevation sections according to seasonal snowmelt. Course A is the only variation that fully summits Magee Peak and is used in low‑snow years. The event emphasizes remote backcountry travel and variable terrain.
Beginning in 2027, all entrants must complete either 8 hours of trail work or 12 hours of race volunteer service; full submission instructions and deadlines are in the Runner’s Guide. Runners must have the GPX file downloaded on their watch or phone. The Runner’s Guide also contains aid station, drop bag, crew, and pacer information. All Intermountain Endurance events are cup less races so runners should plan for a reusable cup.
Camping at Burney Mountain Guest Ranch is provided as dry camping for runners and crew on the listed event nights; the ranch also offers paid lodging upgrades with a stated discount for runners. Entry fees are listed with the event and entries are non‑refundable; deferral and transfer options are available within published time limits.
