One Tree Hill actress Sophia Bush has declared she's training for a half-marathon! The self-professed non-runner plans to run the 13.1-mile 2010 North Carolina Battleship Half-Marathon come November in an effort to raise money for the people of the Gulf Coast via the Global Green USA charity. Bush wrote on her blog, "They need all the help they can get. So I'm running. For the Gulf. For all of you. Because when my lungs start hurting, and my legs start screaming 'this running business is BULL, Sophia!' I think of all of YOU." Find out how you can donate now.
