After claiming the 1500m gold medal in 2011 and the silver medal in 2013, Simpson had high expectations entering the 1500m final at the 2015 World Championships. Her shoe came loose, however, and she had to kick it off with about 600m left while only trailing the eventual winner, Genzebe Dibaba. She kept running, even as the track ripped her skin, and placed 11th.

Simpson was the American steeplechase record holder until Emma Coburn ran a better time earlier this year.
Simpson often celebrates by forming the shape of a heart with her hands.
“In the last 200m of a race, her eyes change and she becomes this different person. She is just an animal fighting. She is an incredible athlete that last portion of the race, and sometimes she’s so focused that it doesn’t matter what happens and I’ll have to tell her she won. And she’s like, ‘What? I won?’ She’s so in the moment and so fierce and such a great competitor that sometimes she doesn’t even realize that she won a race right away. She’s just so in the moment of the race, which I really respect about her.” –Emma Coburn
