E51 | Fueling for Endurance: The Science of Carbs, Recovery, and Performance

The quest for optimal running performance often leads us down paths of trendy supplements and one-size-fits-all nutrition plans. But what if the real secret lies in personalization? Dietitian and ultra-marathon coach Rachel Laymon cuts through the noise with evidence-based, practical advice on fueling strategies that actually work.Ever wondered how many carbs you should consume during an ultra? Rachel suggests starting with 90 grams per hour—but emphasizes this number should be tailored to your unique physiology. A 135-pound runner has dramatically different needs than someone weighing 205 pounds. This individualization extends to all aspects of nutrition, from pre-race routines (where some elite runners swear by Red Bull over coffee) to recovery protocols.Speaking of recovery, those post-run nutrition windows matter more than you might think. Rachel reveals that consuming protein within 30 minutes after finishing your run can dramatically improve recovery, yet many runners—especially morning runners—miss this opportunity as they rush to start their day. Similarly, proper electrolyte replacement through products like LMNT can be game-changing for performance and overall energy levels.Perhaps most surprising is Rachel's emphasis on strength training as a non-negotiable component of running success. With adults losing 3-8% of muscle mass every decade after age 30, even one strength session weekly can yield significant benefits. She offers practical advice for beginners and time-crunched athletes on how to incorporate effective strength work without overwhelming your schedule.Ready to move beyond trendy supplements like sodium bicarbonate and focus on evidence-based approaches that actually improve performance?
