(01:21:10) What to do if you miss workouts or get sickCoach Jonathan sits down with CEO Nate Pearson to answer the biggest questions athletes have about TrainerRoad AI, pulling back the curtain on how it actually works and what it means for your training. They explain why TrainerRoad’s AI isn’t a chatbot or large language model, but a purpose-built system trained on tens of millions of workouts and rides to predict the right workout for the right day, with guardrails that avoid “AI slop.” The conversation dives deep into FTP—why the AI doesn’t truly use FTP the way athletes think, why FTP can go down without fitness going down, and how precision and consistency matter more than chasing a number. They also cover progression levels, post-workout surveys, predicted difficulty, yellow and red days, missed workouts, illness, and why plans change dynamically as you train. Throughout, the focus stays on what matters most: progressive overload, recovery, and building fitness you can actually use, with practical advice to help athletes trust the system, train smarter, and keep getting faster over time.// RESOURCES MENTIONED- Sign up for TrainerRoad! ⁠https://trainerroad.cc/GetFaster⁠- Follow TrainerRoad on Instagram 📸 https://www.instagram.com/TrainerRoad - Join the TrainerRoad Zwift Club 🚴 ⁠https://trainerroad.cc/trzwiftclub⁠ // TRY TRAINERROAD RISK FREE FOR 30 DAYS!https://trainerroad.cc/GetFaster⁠ TrainerRoad is the #1 cycling training app. No other cycling app is more effective.
