Episode notes
Jim Walmsley's Comeback Finish
- Jim Walmsley staged a dramatic late-race surge at OCC after being passed, running all-out for the final 4 km and winning.
- His finish showcased elite mental strength and range across distances.
Small Studies Can Mask Carb Benefits
- A recent small crossover trial claimed no performance difference between pre-run low- and high-carb meals, but low sample size limits conclusions.
- Visual data showed most participants ran faster after high-carb, suggesting the study lacked power, not that carbs don't matter.
Use Short Regular Passive Heat Sessions
- Use 20–30 minute sauna or hot tub sessions several times per week to gain heat adaptations without excessive risk.
- Monitor heart rate (e.g., ~110 hot tub, ~120 sauna) and hydrate; avoid overdoing progressive overload in heat.
