Episode 35: Overtrained or Just Under-recovered? The Difference That Could Save Next Season


Listen Later

Overtraining syndrome is rare, serious, and can end your endurance career if you're not careful. In this episode, we break down the differences between functional overreaching (proper training), non-functional overreaching (under-recovery), and true overtraining syndrome (OTS, and again, it's really rare!). You'll learn the warning signs that separate temporary fatigue from something far more concerning, plus we walk through actual case studies of athletes who took years to recover from OTS. We cover the psychological patterns that lead to overtraining, a return-to-training protocol that can get you back on the right track safely, and why consistency beats intensity every single time. If you're training hard right now or coaching athletes through big training blocks, this episode is the reality check you need before it's too late, for you or for your athletes! #triathlon #overtraining #endurancetraining
