If you haven’t thought much about power as it relates to your running, you’re not alone. As runners, power isn’t something that we often consider in our training.  To help us understand power, we have David Roche with us today. David Roche is an elite trail runner, author, and running coach. He is a two-time USATF trail national champion and the 2014 Sub-Ultra Trail Runner of the Year. David publishes regularly in Trail Runner Magazine and wrote the book, The Happy Runner, with his wife Megan. He also contributed to our Little Black Book of Recovery & Prevention. Although the subject of power and mechanical output may sound daunting, never fear! David breaks down the concepts in a way that makes it understandable, approachable, and easy to apply to your running year-round. We discuss: The definition of power and mechanical output, both in theory and in practicality for runners Why power is a bigger limiter for non-elite athletes How most benefits of developing power come from very short work intervals Why maintaining power is your key to longevity in the sport The success of the Norwegian system using power development Five way to consistently improve your own power David is insightful and enthusiastic when it comes to discussing the technical aspects of running. You're bound to learn something new to apply to your own training!

Thank you DrinkLMNT! A big thanks to DrinkLMNT for their support of this episode! They make electrolyte drinks for athletes and low-carb folks with no sugar, artificial ingredients, or colors. They are offering a free gift with your purchase at DrinkLMNT. And this does NOT have to be your first purchase. You’ll get a sample pack with every flavor so you can try them all before deciding what you like best.  DrinkLMNT's products have some of the highest sodium concentrations that you can find. Anybody who runs a lot knows that sodium, as well as other electrolytes like magnesium and potassium, are essential to our performance and how we feel throughout the day. My favorite flavor is watermelon salt, but citrus salt is also a banger. I’m drinking one a day now to help me get enough fluids in our dry Colorado air. It’s tasty and delicious and I find that I’m not peeing every 45 minutes throughout the day, which might be an indication I wasn’t eating enough sodium. There’s now mounting evidence that higher sodium intake levels are not unhealthy – and athletes need substantially more than your typical sedentary person. Of course, ask your doctor if you’re worried. But for those athletes running outside in the heat, an electrolyte replacement makes a lot of sense. So check out DrinkLMNT to try their new flavor or get a free sampler pack. Thank You AG1! We’re also supported by AG1, the greens superfood mix.
