6 Hours In The Basin

April 18, 2026
Galisteo Basin Perserve
Santa Fe, New Mexico

Mark your calendar for April 18 and join us for the 6 Hours in the Basin race, featuring a flowy, scenic eight-mile loop set in the Galisteo Basin Preserve, with categories for solo racers and teams.

This will be the 8th annual running of the event and the second hosted by the Santa Fe Fat Tire Society. Proceeds benefit the Commonweal Conservancy, the nonprofit that manages and oversees the Galisteo Basin Preserve, including the 45+ miles of trails.

This event can’t happen without volunteers! There are many ways to get involved, including course support, registration, parking, setup and breakdown, and more. If you’re interested in volunteering, please contact Marisa at marisa.ortiz@santafefattiresociety.org.

We also rely on support from our incredible sponsors. To learn more about sponsorship opportunities, please contact Helene at helene@santafefattiresociety.org.
