Optimizing Marathon Fueling Strategies

In this first episode of The Physiology of Endurance Running Podcast, we explore what the research has to say on how best to fuel your marathon. We cover:

• The pros and cons of fat and carbohydrates as fuel sources
• Why taking on carbohydrates aids performance
• How much carbohydrate should we take on during a marathon
• How to choose which fuel type to take on
• How to plan your own nutrition strategy for training and racing
