Let's make this birthday one to remember.

51 years old (Born on October 24, 1973)

Happy Birthday, Levi Leipheimer! You're still pedaling strong through life’s climbs and sprints—though rumor has it your birthday cake now comes with aerodynamic candles to help you blow them out faster. From conquering California three times over at the Tour of California, to proudly bringing home Olympic bronze in Beijing 2008—you've always known how to shift gears into greatness.

May this year bring fewer flat tires and more podium-worthy moments (even if they're just victories against gravity on steep staircases). Keep riding high; after all these years you're proof that age is merely a number—and Lycra never goes out of style!
