BURT 100 : Bainbridge Island, WA, February 6, 2027
The BURT is a February trail ultramarathon on Bainbridge Island offering multiple distances. The event for 2027 is scheduled for February 6, 2027 and lists the following distances:
- 100 Miler
- 110K
- 55K
The standard BURT course is a 55 kilometer loop that links Bainbridge Island public and some private trail networks. Recent course changes for 2027 include a new boardwalk bridge through Lost Valley that reduces muddy sections and an added fourth climb in the Gazzam area.
The event emphasizes community and a pared-down trail experience rather than large modern-event accouterments. The BURT is held in February each year; organizers note the weather is often poor in that month.
Capacity for 2027 is capped at 65 runners total, with per-distance caps shown as 40 runners for the 55K, 12 for the 110K, and 13 for the 100 mile field. The 100 mile entries are vetted before acceptance and waitlist procedures can apply; the organizers note there are currently no open spots.
Registration fees for the BURT are directed to the Bainbridge Island Parks and Trails Foundation's Trails Fund, after deduction of applicable state tax, the registration platform fee, and optional event purchases. Volunteer opportunities exist before, during, and after the event. Visit the organization's website for the most recent information.
