01 / The format

No set distance. Just the next hour.

Every hour, on the hour, runners set off on the same 4.167-mile loop.

Finish inside the hour and the rest of it is yours to eat, rest and get ready. Miss a start or run out of time, and your race is over. It continues until one runner is left.
