The main subject of Fitz Ultra, Matt Fitzgerald has run more than 20 marathons in his life.  He has not, until now, run one by himself.  We dive into every question we could think of logistically, mentally, nutritionally, and otherwise as to how it went and how you can do this too.  It's not as crazy as it seems, especially when you are training for a 50 miler.  WE also talk about a concept training run, the "open loop". What is it and why should you try it for your training. Enjoy the Fitz Ultra episode.
