Get ready to test your endurance on the famous Bonneville Salt Flats during this unique overnight adventure! You'll run as many laps as possible on a scenic, flat 2-mile loop from dusk until dawn (about 11 hours), either solo in the Ultra or as part of a relay team of 4, 6, or 8 runners—just make sure to finish your final lap by sunrise for it to count. Your team strategizes the running order and pacing however you'd like, and while you're logging miles under the stars, non-running supporters can grab Party Supporter wristbands to enjoy all-night activities like a scavenger hunt and astronomy tours, plus everyone celebrates with a charity pancake breakfast and the winning team in each category takes home a trophy!
