This was one of our all-time favorite episodes! We discussed takeaways from our 10 top endurance performance and health studies of 2025, full of science, recommendations, and debates.

We don’t want to give away the countdown, but this one had everything! We’re talking fueling, training, brain health, colon health, and shoes. You just know there had to be a shoe study. Running shoes are 92% of David’s personality.

Our mission was to summarize the science in a way that would help you take the research into the real world. We think that if you can stay 1-2 years ahead of widespread adoption of new scientific principles, you can always have an edge even as the world starts to catch up. Plus, it’s fun! Not as fun as a colonoscopy, but still fun!

We also talked about 3 pieces of running news, including Shelby Houlihan’s first trail race, a new bicarb energy bar, and Ann Trason’s 100 mile performance.

We love you all! HUZZAH!

Topics this week: what we’d save from a fire, a hot-tub experiment follow-up, Megan’s exciting news, whether we’d ever try triathlon, a vest that ejects gels, heat training submersion levels, hemoglobin A1C and REDs, iron supplementation, uphill treadmill effort and timing, scheduling rest days, a supplement hypothetical, Nomio v. sodium bicarbonate, cycling metrics, running power meters, running form changes, tart cherry juice hacks, training on a through-hike, limiting aid station support, and a beautiful listener corner message.

Thank you so much for being here in 2025! May your holidays be like the water in our hot tub: ELECTRIC.

We love you all! HUZZAH!
