On the cusp of turning 30, the dawn of beer bellies and bad fitness injuries for us mortals, Allyson Felix is killing it. Competing in the 100m, 200m and 400m, this American athlete is the 2012 Olympic champion for 200m, a 3 x world champion and 2 x Olympic silver medallist (both also for 200m). This year, she took the gold for 400m at the World Championships which she ran in under 50 seconds. She ran 400m faster than most people go to the toilet.
