What is this Backyard thing?

The backyard ultra is an ultradistance event where each competitor runs laps on a set course of 4.167 miles. Each runner must finish each loop in less than an hour. The distance of each loop is equal to 100 divided by 24, so that a competitor will run 100 miles over a full day (24 hours) if they can.

All backyard ultras all over the world follow the same rules. At the start of each hour, the runners line up again to complete the same loop. A whistle is blown at 3-minutes before the hour, again at 2-minutes before the hour and then at 1-minute before the hour. If a runner is not in the corral when the next lap begins, on the hour, they cannot continue and their race is done. This keeps going until there is only one runner remaining. This runner is then declared the winner. The race continues for as long as is required for there to be only one runner left.
If there are no runners that can complete a final lap within the allowed hour, then there is no winner.

Event's current local time: 6:55 AM MT
