Happy Birthday, Kristin Armstrong! You're the only cyclist we know who can pedal faster than most people drive. Winning Olympic gold in Beijing 2008 wasn't just impressive—it made us all wonder if your bike secretly had rocket boosters attached!Your incredible determination and unmatched speed have inspired countless fans around the globe. May this birthday bring you as much joy as standing atop that podium did—though hopefully with fewer sweatbands involved. Keep pedaling through life with humor and grace; after all, age is merely a number...and you're clearly great at racing against numbers! Have an amazing day!
