Zach Bitter completed 402.5 laps of a 400m track in the span of 12 hours, completing the 100-mile race in 11:40:55.
If you thought running for 12 consecutive hours is tough, try running it in circles entirely on an oval track.
At the Desert Solstice Invitational in Arizona, Zach Bitter ran an American track record in the 100-mile (160 kilometres) running 11:40:55, 4:35 per kilometre pace (7:01 per mile pace).
That’s 402.5 laps of the track. Bitter won $600 USD for his efforts.
The only escape of running for 12 consecutive hours? Turn around and run the opposite direction (Bitter can be seen running both clockwise and counter-clockwise in the highlight video).
