Is it humanly possible to run 100 miles without consuming a single calorie? Would it be possible to run 100 miles in under 24 hours without consuming a single calorie? On May 8th, Mike McKnight set out to find out, and Mike, who is the record holder of the Triple Crown of 200’s, not only accomplished this extraordinary feat, he did it in 18 hours and 37 minutes.

So I talked to Mike about why and when he first thought this was possible; how he prepared and trained for the feat; intermittent fasting and his ketogenic diet; some of the criticism he’s received for even attempting this; and what else he thinks might be possible.

Mike McKnight goes on Blister's Off The Couch Podcast to discuss how and why he ran 100 miles without consuming a single calorie.
