In this week's rebroadcast of the Fit Fat Fast podcast,  the amazing ultra-runner Nikki Kimball comes on the show to talk all things ultra-running, including how she got started, how the human body adapts and breaks through barriers and most important, how to use the body’s stored fat to fuel ultra-distance races. They wrap up by talking about her epic journey of running an ultimate challenge on Vermont’s 273 mile Long Trail!  Jon and Debbie also discuss a Shakespearean topic: During long runs, to eat or not to eat?  That, is the question.
