321. Stop Winging Your Fuel: The Science of Gut Training & Sweat Tech

How do you approach your marathon fueling strategy? If you’re like a lot of distance runners, your routine might look something like this: log your long training miles on nothing but water and sheer willpower, and then just pray your race-day gels work. In this episode, Leticia and Ryan sit down with Tasha, an expert from Precision Fuel & Hydration, to break down why a "one-size-fits-all" fueling plan doesn't work, why under-fueling your training blocks holds you back, and how to properly train your gut to handle race-day demands. Whether you're targeting a fall major or gearing up for the Valencia Marathon in December, this episode will completely change the way you look at endurance nutrition. * The Precision Origin Story: How a near-fatal case of hyponatremia (low blood sodium) led founder Andy Blow to pioneer personalized hydration. * Sweat Rate vs. Sweat Concentration: Why your unique sodium loss is genetically determined and stays stable, while your fluid loss changes with the weather—and the massive "heat myth" runners fall into. * Gut Training 101: The step-by-step method to teach your stomach to comfortably absorb 60 to 90 grams of carbohydrates per hour without GI distress. * The Power of Decoupling: Why separating your energy intake (carbs) from your electrolyte intake (sodium) is the ultimate secret to a flawless stomach. * Race Day Logistics: The science behind morning-of sodium preloading to boost blood plasma volume, and how to successfully manage hydration if you don't want to carry a bottle.

"Your Story Your Why " - Tommie Runz - Episode 4

What happens when you trade addiction and "thirst traps" for 100-mile mountain races and intentional, community-driven content? In this episode, we sit down with Tommie Runz (formerly "Tommy Guns"), an ultra-marathoner, content creator, and founder of PR Project, who is gearing up for the legendary Western States 100 in June. Tommie opens up about his profound journey toward sobriety starting in 2017 and how finding running a year later completely shifted his life's trajectory. From running a 3:13 in his very first marathon to surviving a grueling 340-mile solo trek from LA to Vegas on the Speed Project's OG route, Tommie delivers a masterclass in shifting your perspective, choosing your own suffering, and staying radically authentic in a world full of manufactured content. He also breaks down his strict requirement for brand deals, his goals for the silver buckle, and why he wants you to run across the finish line with him. 🎧 Listen Now Connect with Us: * Our website: https://www.marathonjournal.com [https://www.marathonjournal.com/] * Instagram: https://www.instagram.com/runningpodcast [https://www.instagram.com/runningpodcast] * YouTube: https://youtube.com/@marathonjournal [https://www.google.com/search?q=https://youtube.com/%40marathonjournal] * Follow us on Strava: https://www.strava.com/athletes/30798607 [https://www.strava.com/athletes/30798607]

320. Runnners' Safety Guide (traffic, crimes, animals, and more)

In this episode, we tackle the essential strategies every runner needs to build an invisible armor of safety on the roads and trails. Whether you are running at dawn, hitting remote trails, or navigating busy city intersections, safety isn’t about training in fear—it’s about being proactive. We dive deep into the tactical adjustments that protect your space, from the "360-degree bio-motion rule" for traffic visibility to protecting your situational awareness from being compromised by technology and predictable routines. We also break down real-world protocols for handling high-stress encounters, including how to handle charging dogs, the critical steps to take if you are physically attacked, and how to defend yourself from environmental threats like cumulative UV exposure. Plus, we look at the actual CDC data on wildlife risks—including the surprising stats on rabies in the U.S.—to give you perspective and peace of mind. Tune in to learn how to stay smart, stay sharp, and ensure you always make it back home for your next run. Key Takeaways * Traffic Safety: Never assume a driver sees you. Run against traffic, make direct eye contact at intersections, and use reflective gear on your wrists and ankles so drivers recognize your movement instantly. * Crime Prevention: Ditch noise-canceling headphones for bone-conduction models, vary your training routes to avoid being predictable, and use live-tracking safety features to share your coordinates. * Animal & Environmental Hazards: Never run from a charging dog; stand your ground and use your gear as a barrier. Protect yourself from hidden threats by treating UV rays as a cumulative injury and applying a sweat-resistant SPF 30+ before you head out.

"Your Story, Your Why' - Lauren Waldron - Episode 3

In our latest Your Story, Your Why feature, D.C.-based runner Lauren Waldron shares how the sport became an unshakeable contract with herself while navigating high-stress public sector roles and tumultuous personal transitions. From buying her first pair of Hoka Gaviotas to setting fierce personal guardrails—culminating in telling an unsupportive partner, "You don't deserve to be at my start line," right before her first marathon—Lauren's journey highlights the profound intersection of running, boundary-setting, and community. After overcoming patellar tendinitis and pushing through a chaotic race morning at her first World Major in Sydney, she dialed in her training with coach Andrew Lomancello to slice a massive 20 minutes off her time at the New York City Marathon just two months later. Today, whether logging early miles or analyzing footwear technology like the Mizuno Neo Vista 2, Lauren views every 4:00 AM alarm as a joint mission with her dog Henry to unapologetically chase greatness.

319. Racing with Wheels - Swiss Silver Bullet Marcel Hug

As marathon runners, we think we understand endurance, pacing, and the tech that drives our sport. But what happens when you take the legs out of the equation and replace them with Formula 1 engineering, 3D-printed hard gloves, and highway-speed descents? In this episode, I sit down with an absolute titan of endurance sports: Marcel Hug, the "Swiss Silver Bullet." He is a 12-time Paralympic Gold Medalist and the most dominant athlete across the Abbott World Marathon Majors. Marcel just matched a historic milestone by winning his eighth London Marathon, and I wanted to bridge the gap between our running community and his world. We skip the fluff and go straight into the sports science. Marcel breaks down why he can race 8 to 9 marathons a year when we can barely survive two, how he navigates extreme downhills at 80 km/h (50 mph) without a steering wheel, and how his custom-molded carbon chassis ensures zero energy loss. If you love high-performance gear, brutal physiology, and the elite mindset, this conversation will completely change how you view marathon speed. * The "Silver Bullet" Trademark: How a simple Christmas gift from his junior coach became a global symbol of dominance. * The 9-Marathon Season: Why the smooth, cyclical physics of a push-rim chair allow wheelchair athletes to race nearly ten marathons a year with minimal joint impact. * Technical Analysis (Chassis vs. Shoes): While we look for energy return in foam, Marcel looks for zero energy loss in his rigid, custom-molded carbon fiber seat. * Punching at 20 MPH: The material science behind 3D-printed hard gloves and how athletes "hit" the push-rim rather than grabbing it. * The Wind Tunnel Discovery: Why F1 aerodynamics forced a shift from solid disc wheels back to open-spoke wheels. * The Strict Mindset of a Champion: A rare look at Marcel's internal dialogue when pushing the absolute limit entirely alone at the front of a Major. My Favorite Moment: "In a daily wheelchair, you grab the wheels with your fingers. With racing gloves, you punch the rim. Every single ounce of energy from your upper body has to go directly into forward movement." — Marcel Hug Connect with Us: * Our website: https://www.marathonjournal.com [https://www.marathonjournal.com/] * Instagram: https://www.instagram.com/runningpodcast [https://www.instagram.com/runningpodcast] * YouTube: https://youtube.com/@marathonjournal [https://www.google.com/search?q=https://youtube.com/%40marathonjournal] * Follow us on Strava: https://www.strava.com/athletes/30798607 [https://www.strava.com/athletes/30798607] * Our website: https://www.marathonjournal.com [https://www.marathonjournal.com/] * Instagram: https://www.instagram.com/runningpodcast [https://www.google.com/search?q=https://www.instagram.com/runningpodcast] * Follow us on Strava: https://www.strava.com/athletes/30798607 [https://www.google.com/search?q=https://www.strava.com/athletes/30798607] Connect with Us:
