    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.

    315. The Science Behind the Maurten Bicarb System with Josh Rowe

    *This episode is NOT sponsored by Maurten* We at Marathon Journal are just very curious about new systems of administration and sciene. In this episode, we sit down with Josh Rowe to explore the science behind the Maurten Bicarb System and why sodium bicarbonate has become one of the most talked-about topics in endurance performance. We discuss: - how bicarbonate buffering works- why acidity contributes to fatigue- the history of sodium bicarbonate in sports science- why traditional bicarbonate caused major GI distress- how hydrogel delivery systems aim to improve absorption and tolerability- what types of runners and workouts bicarbonate may benefit- threshold training, marathon racing, and high-intensity applications -published scientific studies surrounding hydrogel bicarbonate systems- the growing role of delivery science in endurance nutrition This conversation focuses on the physiology, performance science, and practical application behind bicarbonate supplementation—not hype, but the evolving intersection of sports science, engineering, and endurance performance.

    312. How You Can Use the World Record to Smash Your Next PR

    In this episode of the Marathon Running Podcast, Letty and Ryan break down the historic sub-2 hour breakthrough in London and, more importantly, how you can apply those same elite strategies to your own training. We translate the performances of Sabastian Sawe and Yomif Kejelcha into actionable "Middle-of-the-Pack" mechanics to help you become a faster, more efficient runner. We discuss the specific "how-to" steps behind these world records: Mastering the Negative Split: Why Sabastian Sawe’s 59:01 second half proves that "banking time" early is a trap that depletes your glycogen 30% faster. The Bicarb Blueprint: How the new "Bicarb System" technology manages muscle acidity (the "burn") and how amateur runners can benefit from high-pH buffering. Aggressive Fueling: Why the 120g/hour carb standard is the new benchmark and how to "train your gut" to handle more fuel without GI distress. Mental Drafting & Stretch Goals: How to use "London energy" to reframe your psychological limits and use pace groups to handle the "mental math" of racing. If you’ve been stuck at the same marathon time for years, this episode is your guide to reframing what your body is actually capable of achieving. We move past the flashy headlines to give you the technical gear, fueling, and pacing tips used by the fastest humans on Earth. We are launching a brand-new Thursday segment: "Your Story, Your Why". We are moving beyond the elite news to share the relatable stories of everyday runners in our community. Want to be featured? Email Letty at letty@marathonjournal.com.
