Lift Heavy Run Fast is the podcast for athletes who want to get stronger, faster, and fitter by combining strength and endurance training in an evidence-based way. Host Jeroen van der Mark explores the science of hybrid performance with leading researchers, coaches, and high-performing athletes. Topics include strength adaptation, hypertrophy, energy systems, metabolic conditioning, lactate thresholds, recovery physiology, nutrition, and mental resilience. Each episode breaks down complex research into clear, actionable strategies you can apply to your training—whether you’re in the gym, on the track, in the mountains, or preparing for HYROX, triathlon, or a strength-focused race. If you want to train smarter, build a more robust engine, and push your limits as a hybrid athlete, this podcast will guide you with practical insights grounded in peer-reviewed science.

    #3: Why a Big Breakfast Doesn’t Boost Muscle & Liver Glycogen Enough (New Evidence)

    Why doesn’t a big carb-heavy breakfast rapidly restore glycogen — even in well-trained endurance athletes? In this episode, we sit down with Cas Fuchs (Assistant Professor at Maastricht University) to break down his latest research on muscle and liver glycogen restoration, carbohydrate timing, and what endurance athletes think is happening after a hard session… versus what the data actually shows. Cas recently published new work demonstrating that a substantial carbohydrate-rich breakfast after an overnight fast did not fully replenish muscle or liver glycogen within three hours in trained cyclists — a finding that challenges common assumptions in endurance nutrition. We dive into the physiology behind glycogen recovery, the differences between muscle vs liver glycogen, why the famous “90-minute threshold” matters so much for performance, and what this means for athletes training on back-to-back days — from recreational runners to Tour de France pros. If you’re preparing for an ultra, long cycling event, or simply want to recover faster and perform better, this episode will change the way you think about fueling. Topics we cover: Why 90 minutes is a critical threshold for performance and fueling What happens when athletes skip carbs after training Muscle vs liver glycogen: why they recover differently What elite cycling teams do in tight recovery windows How much (and which) carbohydrate you actually need for optimal recovery Practical takeaways for endurance athletes and coaches Links: Research from Cas Fuchs Cas Fuchs Instagram Instagram van Jeroen van der Mark 👉 Coaching 1-1 for hybrid athletes 👉 YouTube: Lift Heavy Run Fast

    #1: 105KM ultrarun training & PR's on SBD: programming & insight of ultra athlete and physio Xander Bijsterveld

    In this episode of Lift Heavy Run Fast, host Jeroen van der Mark sits down with Dutch ultra-athlete and physiotherapist Xander Bijsterveld, who recently completed an extreme 100 km ultratrail in the Swiss Alps with 6250 meters of elevation gain. We dive into his full preparation: training structure, pacing, nutrition, tendon management, and how he stays strong while pushing his endurance to the limit. Xander continues to hit PRs in the gym while taking on brutal mountain ultras — how is that even possible? Topics Was this the hardest challenge Xander has ever done?How he structured his training for a 100 km with massive elevationFlat ultras vs. mountain ultras: what’s the difference?How to prep for elevation when you live in a flat countryManaging tendon load, niggles and accumulated fatigueHow he tapered into race weekXander’s full nutrition strategy (carbs, fluids, electrolytes)His pacing approach for a 10+ hour effortCommon mistakes ultra athletes makeHow he recovered physically and mentally 👉 Follow Instagram of Xander 👉 Follow Jeroen van der Mark 👉 Coaching 1-1 for hybrid athletes 👉 YouTube: Lift Heavy Run Fast
