Seven years later, she's still at it. On Saturday, Sorensen — now a trim 125 pounds — will compete in two races in the Baltimore Running Festival. At 7:30 a.m., she'll run the 5K; two hours later, the 27-year-old New Windsor woman will tackle her 10th half marathon. Both times, as she crosses the finish line, her headphones will play the song "What A Wonderful World," by Louis Armstrong. It's her mantra.
