Episode notes
Use Heat To Maintain Fitness With Injury
- Use heat training at low mechanical load to maintain cardiovascular adaptations while injured, leaning on studies showing gains from heat-stress training.
- Equalize sessions by heart rate, not power, to capture metabolic benefits without pushing the injured area.
Running’s Cumulative Wear And New Priorities
- David reviewed prior MRIs showing chronic degeneration across hips, knee, and ankle, illustrating cumulative wear from lifelong running.
- He reframed future running as cherishing miles and adapting training rather than chasing ever-greater performances.
Practical Fuel Choices For Training And Races
- For on-bike fueling, prefer cost-effective 40 g gels (Beta Fuel) and include caffeinated Enervit gels for race-day boosts.
- Combine feed lab whey with a high-carb mix for affordable post-exercise recovery if you skip pricier products.
