Let's make this birthday one to remember.

50 years old (Born on January 06, 1975)

Happy birthday, Kalib "The Marathon Man" Starnes! We know you're famous for keeping opponents chasing shadows in the UFC octagon and making cardio kings question their treadmills. From The Ultimate Fighter 3 to epic battles that left fighters exhausted (mostly from running after you), you've always been one of MMA's most unforgettable personalities.

Here's hoping this year brings you victories more decisive than a judge’s split decision and happiness more sincere than Dana White's smile at weigh-ins. Whether it’s "going the distance" inside or outside of the cage, we salute your persistence: Nobody outruns Father Time quite like you do!
