Overview

The BURT is a trail running event that harkens back to the days when trail and ultra running was a niche sport for peculiar people who liked testing their limits. We offer distances of 55 kilometers, 110 kilometers, and 100(ish) miles. This event focuses on community, shared experience, and a love of the trails – largely without the accouterments of modern endurance events.

The BURT course is a 55 kilometer loop that links up Bainbridge Island’s best public (and some private) trail networks. Each year, the BURT committee looks to unlock new trail connectors – making each year’s BURT better than the last. And the BURT always takes place in February. The weather should be atrocious, but we always seem to hit a (frustratingly) perfect reprieve.

Join us for the 2025 edition of the BURT! Have some fun. Support the trails. And join our community of peculiar people who like testing their limits.

Volunteer

If you'd like to volunteer before, on, or after the 2025 BURT, please come back here in the future to sign up in a forthcoming google sheet.

Capacity

At this point, we are starting with the same capacity as last year with hopes that our permitting will allow us to expand from 30 to 60 runners. With that in mind, we currently have the following caps in place on UltraSignup:
55k: 15 runners
110k: 10 runners
100M: 5 runners
