END-BACKYARD Ultra : Race information
END-BACKYARD Ultra is a backyard ultra held in McLeod, ND, USA, at the location listed as N County Trail, McLeod. The event uses a fixed loop course of 4 miles, 880 feet (6.7056 km) per lap.
All runners begin each lap together once per hour. If a runner is not in the starting corral when the hour begins, that runner is eliminated. Spectators may remain on site to watch and cheer.
Each lap is considered a single "yard." Individual lap times are not recorded; the event records only how many yards each participant completes. A yard must be finished within the hour to count. The last runner who can complete a yard while others have stopped is declared the winner.
The description focuses on the standard backyard ultra format used for this event: fixed loop length, synchronized hourly starts, elimination for missing the start of an hour, and tracking by laps completed rather than elapsed time. Visit the organization's website for the most recent information.
