About this race
Run the Bonneville Salt Flats, the fastest speedway on earth, challenging yourself or your relay team to cover the most miles from dusk to dawn. This overnight event features a flat 2-mile loop under the stars, from sunset to sunrise. Strategy is key for ultra runners and relay teams of 4, 6, or 8. Non-runner friends and family can join with Party Supporter wristbands, enjoying all-night activities like a scavenger hunt or tours from a local astronomy club, followed by a pancake breakfast for charity.
