On Saturday, August 25th, 2019, Zach set a new world record for the fastest time that a human being has run 100 miles. He did it on a track in Wisconsin in 11:19:13. And once he hit the 100-mile mark, Zach preceded to just keep on running, and he then set another world record: longest distance run in 12 hours (he went 104.8 miles). These are two mind-blowing feats, and you can listen to our conversation with Zach about this on episode 15 of Off The Couch.Fast forward to May 16, 2020, and Zach just set another 100-mile world record: fastest 100 miles ever run on a treadmill. So we spoke to the 34 year old runner just a couple days after his most recent feat to discuss when he first got the idea to attempt this; the biggest differences between running 100 miles on a treadmill vs a track; and his preparation, strategy, and goals for this event.We also have a great discussion about Mike McKnight’s Zero-Calorie 100.And if you’d like to hear more of Zach talking about issues related to peak performance, you should check out his own podcast, Human Performance Outliers.TOPICS & TIMES:When did you first get this idea?
