UK Backyard Ultras

Events listed here are of the standard Backyard Ultra format, as created by Gary Cantrell (aka Lazarus Lake).

Each yard (lap, loop, circuit) starts on the hour, every hour. No time limit.

24 yards over 24 hours adds up to 100 miles. 4.167 miles (6.706km) each yard.

There is only ONE winner, the person that completes one lap more than anyone else. Everyone else is a DNF (did not finish).
