Brianna Grigsby

Tucson, AZArizona

I started running ultramarathons in 2016, just after graduating medical school and a week before starting my family medicine residency! When I learned about the Aravaipa Racing Team, my goal was to join the team, which I did in 2019. I’m currently in my 7th year on the team and love training with and supporting my teammates! I live in Tucson, and the 5 mountain ranges surrounding the city are my favorite places to train. Steep climbs and descents are my preferred terrain! When racing, I enjoy a variety of distances from sub-ultra to 100+ miles. Outside of running, I love to backpack, camp, ready fantasy novels, and cook delicious food.
