Race format

Participants run one loop per hour and must complete each loop within the hour to have it counted. Each runner must be in the starting corral and begin the next loop when the bell sounds.

The last runner to complete a loop within the allotted time is the winner; all others are recorded as DNF with distance covered reported.
