Happy Birthday, Louise Hazel! You may run faster than most people can think and leap higher than them too—but let's face it, your true superpower is making heptathlon look effortless. From hurdling impressively to the podium at the 2010 Commonwealth Games in Delhi (bringing home glorious gold for England!) you've given us memories worth celebrating each year.Seriously though, candles on birthday cakes must tremble fearing how quickly you can tackle a hurdle race—just imagine their panic when they realize exactly who they're facing today! Cheers to another fantastic lap around life's track; here's hoping this year's personal best involves laughter, happiness and lots of cake-induced carb-loading.
