Sari Anderson has a knack for finding her way to the podium. Ski mountaineering? In January, Anderson placed second in the U.S. national champion­ships. Cycling? She won the coed duo category of the 24 Hours of Moab mountain-bike race in 2010 and mopped up a field of pros at the 2008 Mountain Bike Marathon National Champion­ships. She's also won a long list of multisport events, like the 2009 Teva Mountain Games' Ultimate Mountain Challenge and the 2008 Xterra Winter World Championship. That's all the more impressive considering the 32-year-old juggles her training and part-time office-manager work with a full-time job—raising her three- and one-year-old kids with her husband, Ian.

HER SECRET: "My family comes first, so I don't always train as much as I'd like. To compensate I focus on quality, which means working with a coach to cut out junk mileage that won't improve my fitness. My kids are included in 75 percent of my training; towing them behind my bike or pushing them in the running stroller is great resistance training. Being a mom has taught me flexibility, so if a scheduled workout doesn't happen, I don't sweat it. I let it go or ride my bike on the trainer or ski laps in the dark after the kids go to bed. My family accepts my competitive streak. While I say I'm racing just for fun, Ian understands that my drive to win is part of my personality."
