Is heat training a marginal gain or major stressor?

Is heat training the next big performance unlock, or just another way to cook yourself? 

In this episode of Performance Process, Ronan Mc Laughlin sits down with elite coach Jacob Tipper to unpack the science, applications, and pitfalls of heat training. They dive into what actually happens to your body in the heat, the potential gains in plasma volume and haemoglobin mass, and why more athletes are turning up the temperature even in cold climates. From WorldTour race prep to age-group applications, the conversation blends physiology, practical protocols, and hard-earned lessons from coaching athletes like Ben Healy and working with Dan Bigham in preparation for his successful Hour Record attempt. If you’ve ever wondered about heat training, this is the episode for you.
