Let's make this birthday one to remember.

44 years old (Born on March 26, 1981)

Happy Birthday, Mirinda! You're the only person we know who celebrates by swimming 2.4 miles, biking 112 miles, and running a marathon—just for fun! Your incredible victories at both the Ironman Triathlon World Championships and Ironman 70.3 World Championships have left us all breathless (literally). Watching you cross finish lines with gold medals around your neck never gets old.

Here's wishing you another year filled with podium finishes, record-breaking splits, and plenty of cake to fuel those legendary runs. May your birthday be as epic as your endurance—and may no one dare challenge you to a race today!
