Train Easy to Run Fast - Sandi Nypaver

Sandi Nypaver is an ultramarathon runner, running coach, and adventurer. She did sports in school. But it wasn't until she went on a youth expedition with  Impossible to Possible that she got a taste of the mindset to test her limits. (Ep. 129 is where Ray Zahab talks about starting the organization of Impossible to Possible.)

Sandi decided to do an ultramarathon. So she signed up for a 100 mile race and ended up winning.
