About
Experience the unique challenge of running on the legendary Bonneville Salt Flats, renowned as the world's fastest speedway. The course is a flat, 2-mile loop where you or your relay team will aim to cover as many miles as possible from sunset to sunrise in an approximately 11-hour timeframe. You'll be running directly on the salt under a starlit sky, adding to the adventure. Plan your strategy as you wish, organizing team members to maximize your overnight mileage. Enjoy various activities throughout the night, such as scavenger hunts and stargazing tours. Wrap up your experience with a charitable pancake breakfast, and if your team runs the most miles, a trophy awaits.
