 Hiba Hebzi loves to see the look on people's faces when she approaches the starting line of a race. I did a marathon in Ireland in Kildare, and I remember when I showed up to pick up my bib, they were like, you're running the marathon? And I was like, yes, why wouldn't I be? Hebzi is a practicing Muslim, and she races while wearing a hijab. And when she's not training, she works as a neurologist and raises her three children.
