Burney Mountain 100
The Burney Mountain 100 is a 100 mile endurance run held in Cassel, CA. The looped course starts and finishes at Burney Mountain Guest Ranch and travels through Lassen National Forest, the Burney Basin, and the Thousand Lakes Wilderness.
The route totals about 15,000 feet of cumulative climbing and descending. Terrain varies from rocky ridgelines to forest floors and sections above the tree line. Runners pass viewpoints that include Mount Lassen, Mount Shasta, the Hat Creek Rim, and visible lava flows.
A runner's guide provides details on aid stations, drop bags, crew, and pacers. Course maps are available on common mapping platforms such as Gaia and Caltopo. All runners and crew are offered dry camping at Burney Mountain Guest Ranch for Thursday, Friday, and Saturday nights, with the event covering that cost. Runners may upgrade accommodations at the ranch and receive a $25 discount for upgrades. Ranch amenities include a restaurant, a salt water pool, laundry, and cornhole.
Nearby points of interest include Burney Falls, Lava Tunnel, Lassen National Park, Chalk Cave, Hat Creek and the Pit River, Baum Lake, and Lake Britton. A post race meal is provided for runners and the ranch restaurant is open for crew and pacers.
Trail work is not required for 2026 but will become a requirement in 2027. There is an incentive for participants who complete eight hours of trail work before the 2026 event. The event has a no refund policy; registration may be deferred up to one week before race day and may be transferred until one day before race start. Registration closes June 16 at 11:59 PM PT.
