Let's make this birthday one to remember.

39 years old (Born on May 08, 1986)

Happy Birthday, Galen Rupp! You're the guy who outran history itself—breaking a 48-year medal drought for Team USA in the Olympic 10,000-meter race. Seriously, most of us can't even run to catch an ice cream truck without gasping for air; meanwhile you're casually sprinting into record books.

From your epic silver-medal finish at London Olympics to dominating marathons and inspiring runners everywhere—you've proven that chasing dreams is best done wearing running shoes (and maybe some aerodynamic tape). Keep setting records and leaving competitors breathless—we'll be cheering from our couches with cake slices raised high. Happy birthday champ!
