You've Heard of Heat Training. Here's How It Actually Works.

Ross McGraw has had one of the more interesting career arcs in the outdoor industry — from Nike's NYC Run program to Vice Media and Viacom, to helping build Hammerhead through its acquisition by SRAM, and now leading commercial efforts at CORE, the company changing how elite athletes think about heat.

In this conversation, Ross breaks down the science of heat training in plain language — why 80% of the energy athletes generate is thermal, how heat zones work, and why the world's best cyclists and runners are training in heat suits before major races. He also gets into what it felt like to go from being a cog in a media machine to betting on himself in sports tech, why triathlon taught him more about business than any corporate job, and how to know when you're doing the "social run" version of your career.
