Stripping down to your undies and jogging through Midtown for charity is a bit of a thing. A sexy thing. Speedo Santas do it in December and now, Cupids in their sexiest Valentine's outfits do it in February.

Hundreds of scantily-clad men and women took part in the fleshy fun on Saturday as Cupid's Undie Run raised more than $120,000 at Rira Irish Pub. It's a 1.5-mile fun run that raises eyebrows and cash for the Children's Tumor Foundation. In its third year of the Atlanta spin-off, the race is part of a national circuit in 30 cities raising more than $1 million.

We collected some of the hottest guys snapped in galleries shot by WSB's Nelson Hicks and the AJC's Jonathan Phillips. Enjoy below and then check out their full galleries here and here.

How do the hunks of the Cupid Run stack up against those from the 5th Annual Atlanta Santa Speedo Run? Judge for yourself.
