Tread Lightly Podcast

As many runners know, a run takes more time than just the miles themselves. You have a pre-run warm-up and recovery nutrition - and so you may wonder if you really need a cooldown after your run, or if you can save some time there. In this episode, we answer a common listener question about what a cooldown after runs actually does - and if you need to do them. We break this discussion into a physiological explanation of what a cooldown does (and what a cooldown won't achieve) and a practical explanation of how to apply effective cooldowns in your training. You will learn:✅ What a cooldown after a run achieves - and what it doesn't ✅ If you need to cool down after an easy run ✅ Why you don't need to worry about flushing out “lactic acid”✅ How cool down miles can improve your running performance✅ Do you need to stretch for your cool down?✅ How to cool down after an interval or tempo run✅ Should you use an ice bath for a post-run cooldown?Thank you to our sponsors:➡️ BodyBio: Research-backed, practitioner-trusted supplements.

Morning runners will skip a pre-run snack for many reasons: gut comfort, time constraints, or the belief that running fasted will make them faster. For years, fasted running was trendy and even recommended. However, science and training theory evolve, and so we're here to tell you in 2025: fed is fastest, and that includes during training. We address some common misconceptions around fasted running.
