Episode Description from the Publisher

*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 nutritionThis 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.Connect with Us:Our website: https://www.marathonjournal.comInstagram: https://www.instagram.com/runningpodcastYouTube: https://youtube.com/@marathonjournalFollow us on Strava: https://www.strava.com/athletes/30798607Our website: https://www.marathonjournal.comInstagram: https://www.instagram.com/runningpodcastConnect with Us:Follow us on Strava: https://www.strava.com/athletes/30798607
