True or False: Performance metrics are important for optimizing outcomes

The title says it all. Everything you should know about the foundations of a good diet from one of today's leading practitioners, nutritionist Nancy Clark, RD.

This is the first episode of Coaches' Corner, a new and ongoing series with several of the top trail running coaches in the world, Krissy Moehl, David Roche, Ian Sharman, and me. Each of these episodes is intended to highlight a specific topic relevant to all trail runners. We start in the form of a T/F statement, get a one-word answer from each coach, and then discuss the nuances that make the real answer less clear. Ultimately, the purpose is to provide you with information that you can apply to your own training. These are also published on our YouTube channel at YouTube.com/ScienceOfUltra The T/F statement for today's episode is: There's a minimum volume of running required before adding any structured workouts (such as intervals or hills) becomes more useful than simply adding more volume

When to walk vs run on inclines, how can poles help, use water in your weighted vest...practical gems from this top athlete and applied scientist.

Marlene Giandolini, PhD and Sebastien Pavailler, PhD are biomechanists who work for Salomon. Today, they bring us insights from their research and the applied intersection of biomechanics, trail running, and shoe design. We discuss everything from trail runner kinematics to shoe drop to foot swelling. So much valuable and new information in this one!

Gianluca Vernillo, PhD is one of the world's leading scientists studying mountain ultra trail runners. Today he brings a vast amount of science and practical insight from his years of studying the uphill, downhill, and other physiologic features of extreme endurance running in the world's toughest mountain courses.

How do the best endurance athletes partition their training? Most of understand what it is to go out for an easy run, but what about intervals. How do the best in the world do it? And, what does the science show about how you should design your interval workouts? What should you do for work duration, rest duration, total work, frequency, and effort level? These are the principle issues we discuss in this episode. And, we wrap up with parting advice from Dr. Seiler that you must hear if you're going to become your ultra best.
