Three Prolific Marathon Runners

We spoke with three marathon runners who have run or are in the process of running 52 marathons in a calendar year. They are racing for a cause by testing the extreme limits of their body. You'll hear about how to get motivated, how they prepared for many marathons and you'll gain insights from their experiences. Join us as we interview Dana Casanave, Dane Rauschenberg and Sam Felsenfeld.
