Burney Mountain 100
The Burney Mountain 100 is a 100 mile loop near Cassel, CA that starts and finishes at Burney Mountain Guest Ranch and travels through Lassen National Forest, the Burney Basin, and the Thousand Lakes Wilderness. The course runs through volcanic peaks, deep forest, high country singletrack, and remote ridgelines.
Organizers use up to four course variations, labeled A, B, C, and D, adjusted each year based on seasonal snowmelt. Course A is the only version that fully summits Magee Peak and is used in low snow years. The event includes approximately 15,000 feet of cumulative climbing and features a mix of rocky ridgelines, soft forest floor, open slopes, and technical singletrack.
The Runner's Guide contains essential information on aid stations, drop bags, crew and pacer rules, and submission deadlines. Runners must have the GPX file downloaded on their watch or phone. All Intermountain Endurance events are cup less, so participants are expected to use a reusable cup.
Beginning in 2027 all entrants must complete either eight hours of trail work or twelve hours of race volunteer service; full details and deadlines are in the Runner's Guide. All runners and crew receive free dry camping at the guest ranch on specified pre race nights, and a lodging upgrade discount is offered to entrants. Nearby attractions include Burney Falls, Lava Tunnel, Lassen National Park, Hat Creek, and Baum Lake.
The entry policy states no refunds, with deferrals allowed up to one week before race day and transfers allowed up to one day before race start. Visit the organization's website for the most recent information.
