A US marathon runner who stripped during a race has been given a jolt with a Taser gun after failing to stop for police, local media reported.

Brett Henderson, 35, was arrested for "public indecency" during the Flying Pig Marathon early May, the Cincinnati Enquirer reported and has pleaded not guilty to the charges.

Nude jogging: not yet considered suitable marathon attire.

When police saw that Henderson was missing his shorts, they ordered him into their car but he kept running, leading them to break out the Taser and subdue him, the report said.

Henderson told The Urbana Daily Citizen he hadn't expected to run naked, but when a pair of borrowed running shorts started slipping off, he wanted to try and finish the race.



"I looked but couldn't find a drawstring ... I kept fighting and pulling on them, and then the elastic gave way so I let them drop," he said.
