Zach Bitter broke a 17-year-old world record for 100 miles by ten minutes last Saturday in Milwaukee, running 11:19:13. He continued for another 40 minutes to set the 12-hour record as well, 104.8 miles. The venue was the Petit National Ice Center, a long-track skating facility that has a 443-meter track around it and is maintained at 50-55 degrees. His average pace was 6:48. Wow. Just wow.
