This episode was such a fun mix of science, emotions, and hot tubs that could cook a turkey! We started with some thoughts on Western States, less than 3 weeks out from the race. Does embracing the stage also mean embracing social media posts telling you that you aren’t being picked to perform well? Our argument channeling Tyrese Halliburton of the Indiana Pacers: the “noise” can be performance enhancing if you have fun with it!

The main science topic was a WILD study on the hot tub improving hemoglobin levels, resting heart rate, and altitude performance. It’s “wild” because the hot tub was set astonishingly high, with participants staying in for an astonishingly long time. I like my participants like I like my eggs: hard-boiled. We talk about what it means and why passive heat training might be the easiest advanced training intervention that goes beyond the basics.

And this one was full of our favorite topics! Other topics: a training trip out to the Western States course, Kilian Jornet searching for a pacer, Cam Jones consuming 185 grams of carbs per hour on his way to winning Unbound Gravel, Jessie Diggins’ amazing poem on fueling her body to take a hit, a study on ketones and altitude that found no benefits, using downhills to improve strength for flat running, and a genetic link between muscle stiffness and strains, plus a Q+A on the new OTQ standards getting faster for men (we don’t like it), whether to GO FOR IT if going for it might not lead to your big goals, a hypothetical about gold medalist Kristian Blummenfelt at a mountain race, and heat and family planning.

The episode finishes up with questions about alcohol and celebrity-flavored bathwater. It’ll make sense soon. Maybe.

We love you all! A unit for a unit,

We gulped down some pungent juice before recording this amazing episode! The main topics were the two big pieces of news: Jim Walsmley won't be racing Western States, and Kilian Jornet is making training videos now. Jim is the GOAT and we gave him an 85% chance of winning just last week. He's the supermassive black hole at the center of the Western States galaxy. Without Jim at the start line, how does it change the race?

Kilian is the GOAT too (yes, we have a GOAT herd), and he just released a training video! He abides by the "no secrets" approach, and we analyzed every frame of that video to try to find clues about whether he might be beatable. Answer: no. Bonus answer: Kilian is the best and it's fascinating that he started his own video series by talking about his heat training.

And this one was full of great topics! Other topics: our magical coaching day at the US Mountain Championships, thoughts on training for mountain races, Unbreakable 2 cancellation, the wild triumph of Simon Yates, a new bicarb gel that could upend the bicarb market, the wild science of broccoli sprouts and a new juice supplement from Nomio, anti-histamines and athletic performance, why we're eating dark chocolate (it tastes good), lung training via breathing devices, the relationship between speed work and form in ultras, a hypothetical about Conner Mantz racing Leadville or Western States, an article in the New York Times on unethical mountaineering, training with a newborn, dealing with life transitions, fitting the Naked Belt, the cost of running, cheaper suphershoes, and an incredible poem on failing and flying.

Everyone forgets that Icarus also flew. Also, if Icarus had broccoli sprouts and Kilian's training video, maybe he would have flown a bit longer.

We love you all! HUZZAH!

This episode was a total joy with toe warmers in all the right places (and some of the wrong ones)! The main scientific topic was a new study on how high carb fueling may improve heat adaptation. We broaden that out to a question from a listener on the old "calories-in, calories-out" framework, and why that doesn't apply to athletes from evolutionary or exercise science perspectives.

The big takeaway from 2 decades of research: avoiding excessive within-day deficits from training may improve health, performance, and body composition. Eat during hard training, or the body may have to take unhealthy steps to avoid shutting down.

And this one was full of great topics! Other topics: a hopeful update on David's knee heading into Western States, the decision to get a cortisone injection, Megan having enough watts to be confused for an e-bike, a new study on weight-vest warm-ups improving running economy, how we think training theory might evolve based on that study, last week's controversial news in trail running, why we think that love and grace for humans needs to lead the way, and a Q+A on fear of vulnerability, workout intensity, and athlete sponsorship.

Stick around to the very end for the hardest we have ever laughed on an episode!

May your knees stay healthy and may your tooth bags stay hidden. We love you all! HUZZAH!
