Anthony DeMaio, head of U.S. sales at Bloomberg Media, talks about running a 100-mile ultramarathon. After dropping out after more than 85 miles the first time he attempted the race, he completed it on his second attempt, in 97-degree weather. "Life and running have similarities," he says. "They're about peaks and valleys, about being in the hole and coming out if it. If you keep moving, you're going to feel better." DeMaio also weighs in on his love of Madonna and the importance of maintaining ties with family and friends even in the middle of intense training.
