Sierra started running ultras in 2015 and has excelled in the 100-mile distance. On this podcast we talk her recent win at the USATF 24-hour national championship, what that means to her and what she hopes to gain from that experience. We also discuss a recent 100-mile race, the Bear 100. This is one of the best stories of mental toughness and resiliency we have ever heard. Sierra is incredibly disciplined; she puts in high mileage and balances her time to train and race. You will be inspired to get those miles in after hearing this one.   IG- @sdegroff
