Todd Ragsdale is claiming a new world's record for running barefoot.
Over 24 hours, he covered 102 miles.
That was 413 laps on the track at Oregon's South Medford High.
He may need a sole retread. Ragsdale's feet are bruised, blistered and swollen.
But he says it's worth it.
Ragsdale used his barefoot run to raise money for the American Cancer Society.
