Zach Bitter, a Wisconsin native, set for new world record for the men's 100-mile run with an unofficial time of 11 hours, 19 minutes and 13 seconds. Pettit Center officials say this shattered the old record by almost nine minutes.
"It's been a six-year journey to try to break the 100-mile world record -- and had numerous failed attempts along the way," Bitter told FOX6 News. "So, it feels good to get it done here in my home state where I ran my first race."
Bitter also set a new record for the men's 12-hour run. While the exact distance has yet to be confirmed, officials say Bitter the record (101.65 miles) by at least three miles.
Bitter told FOX6 News he got his start in running in middle school -- and he later raced competitively for the University of Wisconsin-Stevens Point.
