Coach Caroline and Coach Valerie unpack why sugar and carbs are “making a comeback” in endurance running and why the answer is more nuanced than simply eating more. The conversation walks through the evolution from early-90s carb loading, to spaghetti dinners the night before a race, to the rise of gels and goo, and then into keto, paleo, and the newer high-carb trends you see today. They also explain why a lot of runners have copied elite fueling strategies without matching the volume, intensity, or gut training those athletes actually do.

This episode also covers the practical side of fueling: why elite athletes running 100+ miles a week may need a very different approach than recreational runners, why bicarbonate-based products and “gut training” are part of the current conversation, and why race-day fueling should be practiced during training instead of discovered on race morning. Valerie emphasizes that what works for one runner may not work for another, and that the smartest approach is to test, refine, and stay consistent with the strategy that supports your own running and recovery.
