Cupid’s Undie Run Is the Hottest Race in St. Louis [PHOTOS]

Running shoes? Check. Sunglasses? Check. Pants? Not so much.

Cupid's Undie Run is a charitable event that brings out athletes, exhibitionist and donors because it's a run to raise money for those impacted by NF (neurofibromatosis), a genetic disorder that causes tumors to grow on nerves throughout the body.

The event is held in downtown St. Louis each year and apparently there is no shortage of people in town who are eager to strip down to their underwear and trot around outside in public for a good cause.

After the run came the real fun, with participants bringing the party to Ballpark Village (601 Clark Avenue, STLBallparkVillage.com) where everyone enjoyed a dance party and very few people put on more clothes.
