Diane Van Deren has climbed the highest peak in South America, Argentina’s 22,834-foot Aconcagua. She’s run a who’s who of endurance racing’s top events, including Colorado’s Leadville 100 and Hardrock 100, the latter, with 33,000 feet of total climbing, considered by many to be the hardest 100 miler around (she’s done that one six times). In 2008 she won the 300-mile version of the Yukon Arctic Ultra 300, vowed at the finish she was done with racing in temperatures of 50 below zero, then won the 430-mile version of the same race the following year. Before that she played five years on the women’s pro tennis tour with the likes of Chris Everett, Martina Navratilova and Tracy Austin.
