147. The Science of Overload Training, High-Carb Fueling, and New Caffeine Study!

We brought a jubilant energy to this episode, countering a lack of sleep with a surplus of caffeinated gels! The main training topic was on overload training blocks, which consist consist of volume and/or intensity increases that last anywhere from a couple days to multiple weeks. We review some fascinating studies indicating that overloads may spur breakthroughs, but can also lead to disaster. How do you thread that needle? That's where the science meets art, and where things get REALLY FUN. Rules are meant to be broken! We also discussed how endurance limitations are often just fueling limitations, and why experimenting with higher carbohydrate intakes during activity could change how you think about your physiology. Carbs make champions!

And that was just the start of the excitement! Other topics: a new study on caffeine and health, the relationship between running cadence and endurance, the importance of inclusion, how to think about cross-training, the 48-hour world record, bloodwork and the relation with intensity distribution, why you need to dial in your Zone 2 effort, a question on shoe cushioning for long races, a book recommendation, and much more!

We also discuss the very real, very scientific evidence for why we are entering the GREATEST TIMELINE in the multiverse. It involves kung fu... and something else we probably shouldn't type in an episode description. You'll see, and we think you'll agree.
