Burney Mountain 100

The Burney Mountain 100 is an unparalleled endurance challenge nestled within Northern California’s Lassen National Forest, offering runners a loop through some of the most pristine wilderness and remote landscapes. This race begins at dawn on June 18, 2027, with a start time set for 4:30 am from Burney Mountain Guest Ranch to ensure participants experience the breathtaking sunrise over volcanic peaks, deep forests, and sweeping high-country vistas.
The course is meticulously crafted based on snowmelt conditions, presenting four possible variations (A, B, C, D) that adjust upper-elevation sections as needed. Course A, available only in low-snow years when Magee Peak can be safely summited, offers a rare opportunity to conquer the highest point along this challenging route.
Throughout the 100-mile journey, runners will encounter approximately 15,000 feet of cumulative climbing over varied terrain that includes rocky ridgelines, soft forest floors, open high-country slopes, and deep wilderness singletrack. This dynamic landscape ensures a continuously engaging experience from start to finish, with panoramic views at every turn.
The race immerses participants in the awe-inspiring volcanic landscapes that define this region—views of Mount Lassen, Mount Shasta, Hat Creek Rim, and more are guaranteed along the route. Each mile pulls runners deeper into Northern California’s wild heart, providing a unique opportunity to connect with nature while pushing personal limits.
All competitors must complete 8 hours of trail work or volunteer for 12 hours as part of their race requirements starting in 2027. Detailed instructions and deadlines are outlined in the Runner's Guide, which also provides essential information such as aid station locations, drop bag details, crew rules, and pacer guidelines.
Participants will camp at Burney Mountain Guest Ranch free of charge on Thursday through Saturday nights before the event. The ranch offers a range of lodging options for those looking to upgrade their stay, with all runners receiving a $25 discount. Amenities include dining facilities, a saltwater pool, laundry services, and cornhole games.
The area surrounding Burney Mountain Guest Ranch is rich in natural attractions like Burney Falls, Lava Tunnel, and Lassen National Park, making it an ideal destination for race-cation enthusiasts seeking adventure beyond the trail.
For those unable to attend on June 18, generous deferral options are available up until one week before the event. Transfers can also be made up to a day before the start date, ensuring flexibility without compromising the integrity of this remarkable endurance experience.
The Burney Mountain 100 is more than just an ultra-distance race—it's a celebration of Northern California’s wildest places and a testament to human perseverance in nature.
