Episode 317. Marathon Heat Training: The Heat Adaptation Blueprint
Summer isn’t just a season; it’s a high-stakes training block. In this episode, we break down the science of marathon heat training and why you should view these humid months as the "Poor Man’s Altitude." We move past the marketing hype to explore the physiological reality of thermal stress, plasma volume expansion, and why your watch data needs a serious reality check when the mercury rises.
In this episode, we cover:
•
The Physiology of the Heat: Why your heart rate changes which isn't a loss of fitness, blood plasma volume and how you can take advantage of that.
•
Safety & Red Lines: The critical differences between heat exhaustion and heat stroke, and how to spot the "hidden" dangers of hyponatremia.
•
The Gear Audit: We demystify fabric technology—why GSM (Grams per Square Meter) matters more than branding, the science behind polyester vs. nylon, and why going shirtless is actually less efficient than wearing high-performance UPF 50+ gear.
•
Actionable Protocols: How to calculate your personal sweat rate, the 1000mg-per-liter sodium rule, and the "slushie" pre-cooling method to buy yourself an extra 10–15 minutes of threshold performance.
•
The Effort-First Override: Why you should ditch "Current Pace" on your watch, embrace the 15–40 second per mile "heat tax," and how to use run-walk cycles to stay under your critical temperature ceiling.
