How the 12 hour race works

Participants run the 4.167 loop, starting on the hour every hour, at 7 am. Time between finishing one lap and the beginning of the next can be used to rest, eat, etc. Runners must be present at the start to begin each lap at the top of the hour and will not be allowed to start any lap late. Unlike a traditional backyard ultra, this race will only go on for twelve hours, meaning there may be several winners.
