We provide some context that will be fascinating wh...

We chugged some chocolate whole milk to fuel this amazing episode! The main training topic was on why testosterone levels are relevant for all endurance athletes. While individuals have different genetic set-points for testosterone, studies on men and women show that training and fueling interventions can change baseline levels. Those changes can be positive, leading to more energy and better perf...

We had fire (and iron) flowing through our veins for this awesome episode! There is a big development in the UTMB controversy: reports that legends Kilian Jornet and Zach Miller sent a letter to some of the best athletes in the world considering a boycott of this year's races. We talk about what we think it means through the lens of negotiation theory. This shift in leverage could be a turning...

We ate the world's largest lunches to get ready for this awesome episode! The main training discussion was on tempo running. What even is a tempo? Coaches and physiologists all disagree, leaving athletes in an uncertain spot.

Wherever you look, there seem to be agreements mixed with contradictions, and we sprinkle some spicy controversy flakes on top of it all. Our take? Endurance athletes should probably be doing some strength work, especia...

We loaded up on some fish candy to bring you an awesome episode! The first study of the day blew our minds, showing that just a few weeks of high-dose Omega 3 supplementation reduced some markers of heart stress after steep downhill running. We used to think that Omega 3 pills were boring, and now we have 4 jars in the pantry. Talk about some sexy science! We also talked about Taylor Swift's t...

It's one of our all-time favorite episodes after a whirlwind week! The main topic was David's race at the McDowell Mountain 50 Miler, which we use to talk about a ton of different lessons for training and racing. We're talking pre-race meals, pacing, dealing with cramps, what comes after "failure," fueling and hydration, pacing, and supershoes for trails. Plus lots of trainin...

We turned the hype meters to 11 for this awesome episode! The main training topic was on the wild, uncertain science of post-exercise ketone supplementation. We take you into the cutting-edge of this emerging field of research, like a Magic Schoolbus for the scientific method. Ketone bodies are naturally produced after exercise, an evolutionary mechanism honed over millions of years. Now, through...

We also present some contrasting perspectives from prominent coaches, trying to discern between data and anecdotes, highlighting where there is...

We were extra carb-loaded for this awesome episode! The main training topic was on a new study looking at how strength work changes muscle fiber properties over time. Strength training seemed to reverse the aging clock! We dig into the nuances of what it means and how to apply the findings for endurance athletes of all ages. Invest in a big kettlebell now. The juiciest topic was the upheaval in tr...

Our brain juices were really flowing on this great episode! The main story came from the pro peloton in cycling, where athletes are pushing the limits of carbohydrate consumption during hard races. In general, teams closely monitor fueling to get athletes to 100-120 grams of carbs per hour (400-480 calories), and there are hints that some are pushing the limits even farther. What can we learn? Our...

We put on some dinosaur onesies (our business formal) for this awesome Halloween episode! The big discussion was on UTMB's controversial announcement of a new race in Whistler, Canada, on the same weekend as the now-discontinued, grassroots race called Whistler Alpine Meadows. UTMB rode the sport's wave of exponential growth, gobbling up races to incorporate into their World Series. When W...

We brought some Big Party Energy to this great episode! The main discussion revolved around different ways we put research into practice.

We delve into some of the scientific history of VO2 max via a new study, whether you should do shorter races,...

The vibes were STRONG in this episode, even though the ankles were WEAK. It started off with a fun recap of the Grindstone 100k. What happens when an entire season is built around a goal, but it all ends in some delicious failure? Setbacks can be good for the soul, in moderation. In that way, they're kinda like bacon. Even more joyous than that was a full breakdown of Jim Walmsley's UTMB t...

This episode is one of the coolest moments of our lives: interviewing Jim Walmsley! We met Jim way back in 2016, and since then, we have been two of his biggest fans.
