Event Description


Race start: Sept 3, 2021 @ 8:04pm MT
Race end: Sept 4, 2021 @ 7:06am MT

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 team of 4, 6, or 8 will see how many miles you can run from dusk to dawn (~11 hours). The team who runs the most miles in each team category wins a trophy!​


Be prepared: there will be salt. LOTS of salt. You will be running, sleeping, dancing, and partying on salt. It's one of the reasons Dusk to Dawn Relay is awesome! Salt actually cleans up pretty easily, so don't worry...Some people say it's like running on the moon (like any of us know). It's not slippery, packed down in most areas, and sort of feels like running on a trail.


The Base Camp area is the hub of the race - race info & medical tent, DJ, activities, restrooms, water, food, and runner hand-off area. As the race is at night, the Base Camp will be lit with light towers and LED lights (except during the Dark Sky Hour event). The loop course is lit up with small lights on the ground.

Teams can set up camp chairs, canopies, and/or cots at or near the Base Camp. No camping in tents is allowed on the salt, due to BLM restrictions. If you want to camp in a tent, you can do so in the dirt area off of the 3-mile access road.


The parking area and base camp are located about 1/4 mile from the end of the 3-mile access road to the Bonneville Salt Flats International Speedway (click here for directions to the speedway).

Parking will be slightly removed (about 200 feet) from the base camp and starting line to protect the runners. You will have access to your cars to take a nap, retrieve gear, etc.

Course map is not drawn to scale, and the layout may be adjusted slightly from year to year (it's all flat and looks the same, so we try to mix things up a little...)
