Backyard Ultra Series

The Backyard Ultra is a unique trail running experience that is open to all fitness levels. If you looking at doing your first half, full, ultra or crazy distance marathon, then the BU Series gives you the chance to push yourself for "Just One More Lap". ​ Runners are required to complete a lap of 6,706 meters in less than one hour. The lap will be repeated on the hour, every hour, until there is only one runner remaining. The person who run's the most laps - wins. ​
