On this episode, Andrea is joined by a very special guest: Dr. Allen Lim, founder of Skratch Labs. Allen gives us a breakdown on everything nutrition and hydration for endurance athletes. How should you fuel before/during the run? How do you measure and apply your sweat rate to how you hydrate? What role does protein play in recovery? And much more!
While working as a sport scientist and coach for a professional cycling team, Dr. Allen Lim started making his own training food and sports drinks from scratch for the cyclists because too many of the pre-packaged sports bars and drinks that were marketed or given to them were laden with artificial ingredients and literally making them sick to their stomach. Eventually, he started making a “secret drink mix” in his kitchen using a recipe with less sugar, more sodium, and no artificial sweeteners, flavors, or colors, with a simple and clean taste created by using real fruit. Soon, word of the "Secret Drink Mix" was spreading fast and it was clear that the demand for our all natural drink mixes extended far beyond cyclists or endurance athletes. To meet the growing demand, Allen put together a team of close friends and they decided to let the secret out by opening a little company in Boulder, Colorado called Skratch Labs.

Max-stack shoes are everywhere and from every brand these days. And even what "maximal" means has changed with the standard midsole thickness creeping closer and closer to 40mm. Nathan and Matt take a look at what "maximal" means now, how our physiology and mechanics change using these shoes, how they effect injury risks, and how much caution runners (especially new ones) should exercise with them. Nathan also gives us his Wisconsin-honed cold weather clothing tips for staying warm as the temps start to drop.

Ever had a shoe that everyone recommends only to finally try it out and be disappointed? How is it that one person can love a shoe and someone else loathe it? Matt & Andrea dive into how and why we feel things about our running shoes. They take a look at how biomechanics, gait, shoe construction & geometry, and more impact how we perceive the ride, speed, comfort, and softness of a shoe. They also compare & contrast their thoughts on a handful of specific shoes like the New Balance Rebel V4 and the Mizuno Wave Rebellion Flash 2.

Between super racing shoes and super trainers, it seems like half the shoes on the market have super foams and/or carbon plates. But, what if spending too much time in these maximally performing, fun shoes, might be doing us a disservice? Matt and David look into the research and share anecdotes from their own training on how super shoes have affected them. Then they take a look at some of the excellent non-plated, lightweight trainer options like the New Balance Rebel v4, Topo Cyclone 2, and more.

On this episode, Nathan and Matt have the privilege of interviewing Dr. Wouter Hoogkamer about his research on super shoes and how they affect running performance. They discuss what makes a super shoe "super" (the plate, the geometry, the foam, or all three?). They also discuss Wouter's latest writing and research on getting the best results from running research trials. They get Wouter's take on training in super trainers/plated shoes and how they may effect biomechanics. Be sure to listen to this fascinating discussion on super shoes and research!
Dr. Wouter Hoogkamer is a researcher focusing on biomechanics and energetics of human locomotion and running. He currently leads the UMASS Integrative Motion Lab. If you’ve been in the running shoe space, and are listening to this podcast you likely have heard of one of his most “famous” studies colloquially known as “The 4% Study”, which looked at the original Nike Vaporfly and produced results that gave the shoe it’s name. Beyond research, he is a runner and ultra-runner himself and was the founder of the Trail Ultra Mountain Alliance.

The cushioning of a shoe is the the number one priority for a lot of runners, but there's more to it than you might think. On this episode, Matt breaks down the ins and outs of cushioning. He'll define compliance and resilience. He looks at how different amounts and types of cushioning effect biomechanics, and explores why it may be useful to have a rotation of shoes that feature different midsoles.
