6 Hours in the Basin race

6 Hours in the Basin race

Come ride the fast, flowy singletrack at Galisteo Basin Preserve and help raise money to support the growth and upkeep of these trails. An endurance challenge for racers and mountain bike adventure party for everyone else, the 2025 edition of Six Hours in the Basin will kick off at 9 a.m. on Sunday, May 4, 2025.

Sponsored by the Santa Fe Fat Tire Society, the loop course starts at the Cowboy Shack Trailhead and traces nine miles of the finest trails at GBP. Whether you choose to take the challenge solo or as a relay with a partner or team (up to 6), the goal is to log as many laps as possible before 3 p.m. sharp. With a range of categories, discounts for juniors, food trucks, music, and awards, it’s a full day of two-wheel fun and a great way to support our trail community.

All profits go to Commonweal Conservancy, the steward of the nearly 50 miles of singletrack on this land. Whether you’re in it to burn the fastest lap or just want to soak up some sun and good vibes with like-minded friends, join the Santa Fe Fat Tire Society to celebrate the beginning of mountain bike season.

Registration is open now, with free event T-shirts to the first 100 riders to sign up.
