If you’ve been a RunnersConnect fan for long enough, you know one of the main principles we believe in when it comes to marathon training is improving your body’s ability to burn fat as a fuel source while running, especially while at marathon pace. So, how exactly do we do this and what does some of the latest research say? The research in question revolves around the two concepts of Nutrition Periodization and Metabolic Efficiency Training. Together they increase the body's ability to use fat as fuel during exercise and thus optimize both body composition and performance.  Joining us in this episode is Bob Seebohar, the creator of these two concepts. He’s going to help you learn… What these two concepts are and why they are so critical to your running performance. How to utilize them during your training and taper And how tweak these concepts to improve body composition, and reduce GI issues If you’re racing a fall half or full, this is a must listen!
