George Hood's time isn't official yet, but organizers say he spent about 177 hours over eight days riding a spinning bike at a suburban YMCA.
He rode the equivalent of 2,016 miles, burned more than 46,000 calories and never slept for more than 12 minutes at a time.
The retired Drug Enforcement Agency investigator from Aurora began his ride on May 5 and finished early Monday. He was taken to an area hospital as a precaution.
He had held the record until last summer after spending 111 hours, 11 minutes and 11 seconds on a bike. That record was broken by another cyclist from Tasmania.
