USA’s Zach Bitter has just broken the record for running 100 miles (yes, that’s a thing). The 33-year-old completed the distance in 11hrs 28mins 3secs. Bitter is a glutton for punishment and wasn’t happy setting a new 100-mile record: continuing to run a further 4.8 miles to beat his own 12-hour world record as well. His timings were almost too perfect over the 100-mile distance, running a negative split with the second 50 miles marginally faster than the first. Bitter’s 6:48min/mile pace equates to a marathon time of 2hrs 58mins. The record was set at the 6 Days in the Dome event in Milwaukee, where fellow athletes went on to compete on the indoor track for another five and a half days to see just how far they could run. As you do.
