It’s one thing to run a fast marathon at the end of an Ironman. But it becomes extra special when you have to run that fast to actually win the race. Mirinda Carfrae was 14:32 back off the bike and in eighth place at the 2014 Ironman World Championship when she uncorked a course record time of 2:50:26 to catch the long-time leader, Daniela Ryf. The gap between the two at the end? A mere 2:02.
