Trail, it ain't the same no more.

Théo Detienne closes out his season at Mallorca by UTMB, returning to racing after the physical and emotional toll of his UTMB attempt, with minimal preparation and lingering injuries, sharing the experience of running 100 kilometers locked in with a rival before the decisive separation, the shift into survival mode as the gap opens, and the fight to hold on all the way to second place, while reflecting on how trail running is evolving and what matters most beyond the result.
