Andy Baldwin's Underwear Run

Bachelor Lt. Andy Baldwin takes part in a underwear run in Kona on the Big Island of Hawaii on Thursday.

The 30-year-old U.S. Navy hunk looked his usual fit and muscular self, sporting both a pair of skimpy blue Nike swimming trunks for his early morning swim and a black pair of boxer shorts for the Ironman Underwear Parade, which helped raise money for charity. But what is this man looking at?

The underwear run seems to be a precursor for the “Ford Ironman World Championship,” which Andy is set to participate in on Saturday in Kona. This will be his fifth Ironman competition in six years.

As part of his military career, Andy will reportedly be deployed to Iraq in January 2008 for 6-12 months. “He leaves in January,” Baldwin‘s rep recently told Us.
