In this episode, we start with a quick intro to preview Kara Goucher's first marathon in 3 years in Houston and discuss the just-released Olympic Trials course in Atlanta.

Then, we turn to an interview with Zach Bitter, US 100-mile Record Holder. He's an ultra-runner by specialty but we cover all topics with him from training periodization to using heart rate to mental training and diet. 

You will learn how to go long better from this discussion whether you are targeting a half marathon or marathon or ultra-marathon.
