Sri Chinmoy 13 Hour Ultra

Sri Chinmoy Self-Transcendence 7 and 13 Hour Races

The event offers timed loop running in two time-limited formats: a seven hour race and a thirteen hour race.

All participants receive medallions and certificates; awards are given to top finishers in the event age categories of under 60 and 60 and over.
