WINTER I am so excited that we came in first. When I look up toward the back of the pack, I see Mike and Olivia still jogging toward the finish line, looking exhausted and defeated. I almost burst out laughing but manage to contain it to a satisfied smirk. The crew members come over to unbind us, their practiced hands working quickly to free our arms and legs. The relief of being able to move independently again is immediate and wonderful. "Energy station is over there," one of them says, pointing to a set of tables loaded with sports drinks, energy bars, and what looks like professional-grade recovery supplements. I grab a bottle of something called "Peak Performance Electrolyte Complex" that tastes like liquid lightning and makes my eyes water. Nath chooses a more conser
