The Chicago Sun-Times said 49-year-old George Hood is not to be deterred, however.
After pedaling for 85 consecutive hours, Hood received an e-mail from authorities at the Guinness World Records, citing errors in the logbook that documented his ride. Although Hood was careful about documenting his ride -- he even videotaped it -- Guinness authorities said they found inconsistencies with the recording of his rest breaks.
"This has been a very difficult decision to come to as we recognize that this was done with the best of intentions, yet had some fundamental flaws," wrote Guinness records manager Scott Christie. "With great regret, I am afraid that we cannot accept your attempt due to the problems with the rest breaks and log books. I understand this was a genuine human error, but it meant your evidence was contradictory."
Hood, a former Marine, told the Sun-Times he understood and respected the rules. He plans to try again for a record 101 consecutive hours in July.
He said he hopes to raise at least $30,000 to benefit disabled children.
