Episode notes
Use Uphill Treadmill Thresholds
- Do use uphill treadmill threshold workouts to build aerobic base while reducing impact and injury risk.
- Progress workload gradually from ~40 to ~60 minutes per session and control effort with heart rate signals.
Carbs Improve Training Adaptation
- High carbohydrate availability improves adaptation across repeated sessions, not just acute performance.
- Caffeine helps performance in both diets but does not rescue the adaptation deficit of low-carb training.
Dose Caffeine Strategically
- Try 3 mg/kg caffeine pre-session if you want reliable performance gains of ~2–3%.
- Use caffeine gum for quick absorption and for targeted boosts in long events or hard workouts.
