He, and his colleagues, are making discoveries in human metabolism and energy balance that will reshape our approach to human health for many years to come. These are fundamental breakthroughs that are providing…

[Rebroadcast] Our goal is never to get good at suffering. Our goal is to suffer less under the same conditions, not to make running easier but to run with greater ease.

Dr. Baar rejoins us on the show. He was previously on for episode 58. Today we illuminate the central role of connective tissue and associated proteins in transmitting force from muscle, extend that understanding to explain how muscle functions in running (hint: it’s not at all like most people think), and dive into ways that you can optimize your …

Mapping your training and then seeing what events (races, or adventures) fit on your map, without bending it, keeps the focus on what’s most important…you. This method tells you which events you could run because it’s the method that fits events to your body rather than bending your body to fit events. It’s the only approach that will provide a lif…

This is a deep dive into carbohydrate periodization with Drs. James Morton and Julien Louis where we explain the science behind our recommendation of FUEL FOR THE WORK REQUIRED (e.g., enough but not much more) and GLYCOGEN THRESHOLD (i.e., train to low levels). We also explore issues of sex and age, how bone health may be critically dependent on ca…

I sat down with Spring co-founder Rafal Nazarewicz, PhD to talk about using real foods in ultras.

Is overtraining common among ultra runners? Are you running too much? Can adherence to the mantra of consistency open a gateway to overtraining?

How much do your training runs need to look like the race or event to maximize your performance? That's the basic question behind the term 'specificity'. Our four coaches address these ideas in today's Coaches' Corner.By Shawn Bearden

What is the 'long run'; can it be too short; can it be too long? Today we simplify and demystify this enigmatic workout.By Shawn Bearden

How valid are the most commonly held beliefs in exercise training that assume a reliable and specific adaptation to a specific workout - do this workout and get that result ? In this episode, I explain why we now view these ideas as too simplistic. We dig into how the basic principles that underly the majority of exercise training plans owe their o…

Technology gives runners the opportunity to run according to readouts and feedback from devices. To what extent should you use them?By Shawn Bearden

In recent episodes we’ve explored how you can train your mind and body. The third area for training is craft. Everything from pacing, to hydration strategy, to gear choices, to foot care are part of your craft. Today, the part of craft we’re going to explore is downhill running. Downhill running is a skill. It requires deliberate practice and can n…

Is there a general formula you can apply to taper properly for an event? Find out how our coaches approach tapering with their athletes.

You can train our mind, body, and craft. In recent episodes on training your body, we skimmed the surface of training endurance and economy. If you run a lot of miles, often on race-like terrain and run all out for short bursts a few times per week, you’re doing the majority of the work that will improve your body’s capacities. To further extend st…
