PHILADELPHIA — Thousands of bicyclists in various stages of undress have pedaled their way around the city to promote fuel conservation and positive body image.

The Philly Naked Bike Ride on Saturday featured people sporting masks, underwear, body paint, glitter or nothing at all. A lot of riders wore just their shoes.

Debbie Kaighn, who was riding in the popular annual event for the third time, wore shoes, socks and body paint.

The 12-mile ride through the City of Brotherly Love is among many related to the World Naked Bike Ride movement. Riders on the twisting course wheeled through University City, around the Rittenhouse Square park, down to City Hall and through Chinatown. Giddy crowds cheered them on while shooting photos and videos on their cellphones.
