I ran into Ellen Jaffe Jones at the Raleigh NC Vegfest, where she was inspiring young and old to get off their butts and embrace a healthy, active, vegan lifestyle. We had met on Skype for a podcast interview more than three years ago, but this was the first time we had met in person.

And since I've become a runner, I badly wanted a copy of her new book, Vegan Fitness For Mortals. As one of the most decorated track and field athletes in the country (and getting more and more competitive as her non-plant-based rivals slow down and quit as their bodies decline), she has a lot to teach me about running well and sustainably.
