Embracing the Heat: How Summer Training Makes You Faster

July 6, 2026·36 min
Episode Description from the Publisher

If your pace fell off a cliff the second it got hot out, you're not losing fitness. You're adapting! Amanda, Chelsea, and Dr. Chris break down the summer slowdown, the very real reason your easy runs suddenly feel brutal and your heart rate spikes for no obvious reason. They get into what is actually happening in your body when you train in the heat, why it is diverting resources just to keep you alive, and why pushing through it is one of the most effective things you can do for your fall race season. Plasma volume expansion, improved sweat response, glycogen sparing, and why heat training works a lot like showing up to a lighter planet after training on a heavier one. Slower in the summer does not mean less fit. It means you are handling a whole extra set of challenges, and building something that pays off when the temperature drops.
