After countless hours of research and tweaking, I believe I have developed a better table of the perceived temperature when running. This is currently in beta form, and I will continue to enhance it and put more details into the explanations, but I expect it replace the current ‘Perceived Temperature For Runners’. This new approach takes into account your height, weight and pace, all critical factors in how the heat affects you.
