Dusk to Dawn Relay + Ultra 2026

The course is a beautiful, flat 2-mile loop on the Bonneville Salt Flats - the fastest speedway on earth - on which you (Ultra) or your relay team of 4, 6, or 8 will see how many miles you can run from dusk to dawn (~11 hours). You will run directly on the salt overnight under the stars, from sunset to sunrise. The team who runs the most miles in each team category wins a trophy!​​​​

For your non-runner family and friends who still want to come and enjoy the night and support you - get a Party Supporter wristband!

In order for your final lap to count, you must finish it by sunrise. Otherwise, you make your own strategy. Decide who will run when, how many laps, who will start, finish, etc. It's up to you! Get together and figure out how you can run the most miles from dusk to dawn.

Enjoy all-night activities such as an ultimate scavenger hunt or tours of the cosmos from a local astronomy club, win awesome giveaway prizes, and enjoy a pancake breakfast for charity at the end of the race.
