Let's make this birthday one to remember.

47 years old (Born on April 23, 1978)

Happy Birthday to the legendary Gezahegne Abera! Your feats are still marathon-sized—even cake slices tremble in respect of your Olympic victory at Sydney 2000, when you effortlessly proved that running 26.2 miles is just a warm-up before birthday parties.

You didn't stop there: by achieving the unique Olympics-World Championships double in marathon, you've shown us humans that superheroes indeed walk (or run!) among us. Wishing you countless more victorious laps around the sun—just remember pacing yourself, marathons and birthdays alike require stamina. Enjoy your day with laughter and smiles; we guarantee no one will challenge you to a race today!
