Happy Birthday, Susan! You're the only person we know who thinks a 1,150-mile dogsled race through Alaska is just another walk in the park. Winning the Iditarod not once, not twice—but three times? Clearly, you're either part husky or secretly powered by birthday cake!Your incredible determination and trailblazing spirit have inspired countless adventurers (and couch potatoes) alike. May your special day be filled with laughter, joy—and perhaps fewer frostbitten toes than usual. Here's to you—our favorite musher whose achievements will always lead the pack!
