Overheating is one of the biggest but least understood limiters in ultra endurance racing. In this episode, we dive into why your rising core temperature quietly erodes performance, how heat adaptation works, and what protocols you can use to train smarter.

You’ll learn:

✅ Why heart rate, core temp, fueling, and performance are linked

✅ The difference between active and passive heat conditioning

✅ How to monitor progress with aerobic decoupling (Pw:Hr ≤ 5%)

✅ Practical base, maintenance, and race-specific protocols

✅ Why measuring matters — and how the CORE sensor helps you push safely

This is part 1 of a 3-part performance series:

1️⃣ Heat adaptation

2️⃣ Hydration strategies

3️⃣ Nutrition for hot conditions
