Happy Birthday, Susan! You're officially another year stronger and wiser—though we're pretty sure your bronze medal from the 2004 Athens Olympics still shines brighter than any birthday candle. Who knew swimming, biking, and running could age someone so gracefully?Your incredible triathlon journey continues to inspire us all; clearly you've mastered endurance not just in sports but also at staying forever young (seriously though—what's your secret?). May this next lap around the sun bring you as much joy as crossing that Olympic finish line did. Keep racing through life with humor and heart—we're cheering for every milestone ahead!
