Prépa Hivernale ⛷️ : tout ce que doit faire un Traileur pour progresser ! W. Arthur Joyeux-Bouillon & Gédéon

·1 hr 1 min·4 clips

Two elite mountain athletes reveal how trail runners should use ski mountaineering to dominate their winter training.

1. Dans la Tête d'un Coureur features Arthur Joyeux-Bouillon and Gédéon Pochat discussing winter training preparation for trail runners in the context of ski mountaineering. 2. Arthur Joyeux-Bouillon is a professional trail runner based in Chamonix, Savoie, competing at elite level and recently became a father; Gédéon Pochat is a Savoie native competing on the World Cup ski mountaineering circuit in winter and in ultra trail races in summer. 3. The episode's central question is how trail runners should approach winter preparation, whether through ski mountaineering, running, or a structured hybrid, and what mistakes to avoid. 4. Arthur frames fatherhood as 'the longest ultra trail of his life — 20-25 years according to his friends' and describes how two months of unexplained infant suffering reset his mental approach to pain in races. 5. Arthur's conclusion from fatherhood is absolute: if he takes a race start, he will finish, because unlike his baby's suffering, his own pain is entirely chosen. 6. Gédéon identifies the ski-to-trail transition as the highest-injury-risk period for ski-trained athletes: cardiovascular fitness peaks during ski season, but ankles are locked in rigid boots for 4-5 months, creating a 'Ferrari engine in a Clio chassis' mismatch. 7. Gédéon reports developing synovitis in both knees at age 30 when returning from ski season, which resolved once he maintained one to two short running sessions per week through winter to keep the neuromuscular patterns active. 8. Arthur recounts that his 2019 heavy ski winter — anchored around the Pierra Menta race — left him unable to complete summer ultra trail races due to accumulated cold-weather fatigue and likely nutritional deficits. 9. Both athletes agree that ski fatigue is 'traître' — treacherous — because the absence of muscle soreness means the body accumulates chronic baseline tiredness with no obvious warning signal. 10. Arthur's winter training structure is entirely weather-driven: he checks the morning avalanche bulletin and builds the day from the forecast, with no pre-planned sessions. 11. Arthur's weekly template includes long 5-6 hour ski sessions on clear days accumulating 4000m of elevation gain, threshold sessions of 5x200-300m vertical repeats in zone 4 on shorter days, and always two running sessions per week on foot. 12. Gédéon's winter training is more structured due to World Cup competition: early season volume-focused, progressing toward threshold and PMA work, with a typical week including one PMA session, one threshold session, and volume base before races. 13. Both athletes note that ski mountaineering sessions never last under 90 minutes — the time required just to prepare skins, review the route, and dress appropriately makes shorter sessions impractical. 14. Arthur emphasizes that ski mountaineering days of 4000m elevation gain produce no muscle soreness, making it easy to underestimate accumulated fatigue — leading athletes to return to running too hard too soon. 15. The discussion of energy management in winter highlights thermoregulation as a significant additional caloric cost: shivering is identified as one of the highest-energy demands the body can face, adding to already substantial athletic expenditure. 16. Kylian Jornet and François Daen are cited as examples of elite UTMB winners who are also ski mountaineers, contributing to the perception that winter skiing is a prerequisite for summer ultra performance. 17. The episode has a collegial, peer-to-peer conversation tone — three practitioners sharing field experience rather than textbook periodization theory, with occasional humor about undisclosable ski-mountaineering sayings. 18. Both guests draw on personal mistakes and lived experience rather than abstract principles, giving the advice a practical rather than academic character. 19. Trail runners who want a real-world training framework from two elite mountain athletes combining ski and ultra will find detailed, replicable session structures here. 20. Runners based in flat urban environments, or those looking for non-winter-sport training alternatives, will find less directly applicable content.
