About Backyard Ultra

A Backyard Ultra consists of a 6.7km (4.2-mile) loop that should be completed in a 60-minute window. Every hour, a whistle signals runners off the course, beginning the start of the next loop. Runners complete each loop at their own pace and leisure, and will continue the race for as long as they keep getting back to the start/finish line. Some have tens of minutes of rest, others tens of seconds.
