In today’s episode, I talk about junk miles — what they are, why they might be slowing down your progress, and how to make sure every run you log has a purpose. We’ll break down the “gray zone” in training, explore the science of fatigue versus adaptation, and share practical tips to avoid wasting time (and energy) on miles that don’t help you get faster, fitter, or stronger. Whether you’re chasing a marathon PR or simply want to train smarter, this conversation will help you run with intention and see better results.
