NAPERVILLE, Ill. (AP) - A suburban Chicago man has reclaimed the Guinness world record for time spent on a stationary bicycle.

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.
