The BURT 100, set for February 7, 2026, on Bainbridge Island, WA, offers a challenging yet incredibly rewarding experience across 100-mile, 110-kilometer, and 55-kilometer distances. This event embraces the spirit of old-school ultra-running, prioritizing community, shared experience, and a profound love for the trails over modern endurance event "accouterments." The course is built around a dynamic 55-kilometer loop, continually enhanced with new trail connectors, ensuring each year brings a fresh challenge and more immersive trail time. Runners can expect typical race day conditions with highs around 49F and lows near 37F, and an 18% chance of precipitation, adding to the rugged charm of this winter event.

The BURT course is a true gem, weaving through the lush firs and cedars of Grand Forests, Gazzam Lake, and Fort Ward, while also treating runners to stunning world-class water views at Port Blakely and South Beach. Over 85% of the course is on trails, featuring a challenging mix of single-track, groomed park trails, and some road sections, with 1.5 miles of road being replaced by new trails for 2026. Each 55K loop packs over 4,000 feet of elevation gain, including a "vert crux" of deceptively difficult switchbacks in Gazzam Lake. This hilly island terrain is known for being deceptively hard, with challenging footwork that prevents runners from finding a consistent rhythm. Aid stations are well-stocked but limited, fostering self-sufficiency, and runners are encouraged to contribute to the communal snack spread.

Beyond the physical demands, the BURT 100 stands out for its unique contribution to the local community; 100% of registration fees (minus taxes and platform fees) are directed to the Bainbridge Island Parks & Trails Foundation's Trails Fund, supporting the acquisition, planning, building, and maintenance of the island's cherished trail networks. The race has garnered a reputation for its high DNF rate in the 100-mile distance, a testament to its genuine difficulty despite seemingly moderate elevation statistics. Runners often describe the experience as tough, with dark nights on the course adding another layer of mental and physical challenge, yet ultimately fun and deeply engaging. The BURT 100 is more than a race; it's a gritty adventure and a heartfelt contribution to preserving the beautiful trails of Bainbridge Island.
