Cupid's Undie Run set for scantily-clad start in Buckhead

Hundreds of runners are lacing up and stripping down for a good cause. 

The annual Cupid's Undie Run kicks off at noon on Feb. 12. Runners will race for about a mile, starting at Big Sky in Buckhead, wearing only their underwear. 

The fun run is a funny concept, but its mission is serious. The race raises money for the Children's Tumor Foundation, which funds research for a cure for Neurofibromatosis.

The genetic condition that affects children and has no cure causes tumors to grow on nerves throughout the body and affects one in every 3,000 children.
