The concept is both simple and delirious.

Every hour, runners will start a loop of 6.706 km, which they will have to do and redo, always within a period of 60 minutes, until only one and last runner remains on track: The Last Man Standing. No matter how long it takes.

The event is exactly the same concept as Tennessee's Big Backyard Ultra, organized by the same man who founded the Barkley Marathons, Lazarus Lake.

This is a race where speed is no longer a performance standard, but rather endurance and the ability to manage time and energy. A race to test your limits until surrender.
