We put our party hats on for the ultimate celebration: Podcast Tuesday! The main training topic was on lactate shuttles in the body, and the connection between lactate and fatigue at all intensity levels. It's so fascinating how this molecule connects what we all feel during training, from a professional athlete to someone who is going on their first hike! But the main discussion was on Megan's PhD defense and her research in female athlete health and performance. The study findings = IMPORTANT. The double doctor swag = ACTIVATED. We discuss takeaways from tackling big scary goals! The main one to remember is that wearing black prevents the pit stains from being too obvious.
And you better believe we were just ramping up! Other topics: rapid protocols for heat adaptation and how that may impact performance in all conditions, a new study that connects blood volume to short-term fitness changes, emotional state and performance, our thoughts on a big scandal in ultra running, adaptation to downhill running, dopamine and perceived exertion, the interaction of running and cross training, and a follow-up on training the stomach for people with really bad stomachs. Your farts are not your destiny!
We had such a great time with this one. May your races be cool and your fitness be hot!

151. Blood Volume Science, Emotions and Performance, and Double Doctor Celebration!

Five to ten topics, sometimes about running, with lots of love and enthusiasm and science. We dig deep into training, races, studies, pop culture, and much more! With Megan Roche, M.D. and David Roche!

Running

We sat in a stew of uncertainty before recording this awesome (and healing) episode! The main training topic was a pair of studies looking at longevity outcomes in serious athletes. Extra-hard training seems to have longevity benefits compared to general population lifestyles, contrary to some warnings you might hear! Let's all plan on doing uphill treadmill runs in the nursing home.
The big conversation was in the spirit of sharing all of the ups and downs of life. TW: deep discussions of pregnancy uncertainty. Megan courageously shared her current health status, and how she is thinking about vulnerability in a tough time. Over the last 4 years of this podcast, we have opened up about everything, and our lives have opened up with so much love as a result. We got this, whatever "this" ends up being, even if it takes a while.
And we discussed so many of our favorite topics! Our theory is that talking about interesting things (and making jokes) is restorative. Other topics: Conan O'Brien's commitment to the bit, how the new Jim Walmsley video played a role in our weekend, fitness return after David's accident, caffeinated gels and fueling workouts, AI bots and how we think it may change human interaction as we know it, a new study on sodium bicarbonate and the placebo effect, the Cocodona 250 and multi-day ultras, Zwift's price increases, Emma Coburn's toughness, and hot takes.
There may even be a poetry reading at the end. Stick around to find out... If you dare!
On a day like today, we are even more thankful for the amazing listeners out there who give us strength and courage to wander through the darker forests along the way. We love you all! HUZZAH!

206. Doing Hard Things, Longevity and Training, Fueling Short Workouts, The Power of Placebo, AI Bots, and Cocodona 250!

We celebrated a week with minimal life drama (YAY) before recording this great episode! The main training topic was a new study monitoring response v. non-response. Imagine two similar athletes who are given the the same training program. One could have breakthroughs, and one could face physical disaster. Why? We use the study to talk about how we have seen athletes respond differently, and ways you might be able to understand your own unique physiology. Training theory is such a cool window into how every body is different!
We also talked about metrics we track! Almost every watch has a treasure trove of data if you know where to look. For David, that data helped guide a non-linear post-crash recovery. For Megan, it helped reveal an unexpected pregnancy. For you, it could help you move through the uncertainty of things like response v. non-response with more confidence. Plus, we all love fancy graphs!
And this one was full of fun topics! Other topics: new bike day, a mystery about a signature, why we might want to remain skeptical about AI, 3 shoes we are reviewing, a new study on running economy variance and fatigue resistance in trained v. untrained runners, how combining strength training approaches may be helpful (with possible neuromuscular rationales), a new track league that promises to do everything differently, how questionnaire response rate may influence study outcomes, mixing creatine and caffeine and sodium bicarbonate, and uninformed horse thoughts. 
Stick around to the very end for a special Easter Egg from the editing process. We love you all! HUZZAH!

205. The Mystery of Training Non-Response, Strength Work Approaches, Health Metrics, New Bike Day, and Track Going Mainstream!

We got the surprise of our lives before recording this dazed-and-excited episode! The main topic was the Canyons 100k. It was Megan's dream race, and you may have seen... she did not start. We had some incredibly surprising news right before we boarded our flight to California for the race, and we process it in real-time on the episode. Hopefully the discussion and Megan's openness helps you deal with whatever big surprises you face in life!
Even though Megan didn't race, we cheered and crewed as ultra history was made at the race! This year's Canyons 100k had a performance for the ages from Katie Schide, plus a breakthrough from Rod Farvard, a selfless act from Drew Holmen, and so much more. We break down the dynamics, full of joy from seeing it all live! The big discussions revolve around training theory, fueling approaches, how cooling mattered even in temperate conditions, our complex thoughts on carb loading, hydration needs, and inspiration from the back of the pack.
And we brought a giddy, delirious energy to some awesome topics! Other topics: why we were so surprised by the big news, how Megan feels about it all, societal expectations in early pregnancy, Allie Ostrander's wonderful reflections on crying after races, continuous lactate monitors, the 776 Invitational's huge investment in women's track and what it might mean for the future of the sport, why it's bloodwork season and what people should test, the new ruling making non-competes unenforceable and how it's relevant for endurance sports, the TikTok ban, and hot takes.
Life comes at you fast. Maybe that's why we podcast fast! Knowing you all are along for the journey means so much to us. Into the great unknown we go! HUZZAH!

204. Canyons 100k Breakthroughs, Why Megan Didn't Race, Carb-Loading Thoughts, Bloodwork Season, TikTok Ban, and Big Surprises!

We sipped on some of the finest, chalkiest electrolyte drink for this great episode! The main topic was gearing up for big events, spurred by Megan's upcoming adventure at the Canyons 100k. After the health issues, we were unsure whether we'd ever be able to have this sort of discussion on the podcast, and listeners have been there every step of the way. If there is any test, it's in training. Racing is a celebration. This episode celebrates the broken road to get to the race-day party!
This one was also packed with fun science! The main study helped debunk energy availability cycling, where athletes intentionally reduce energy availability in an attempt to improve power-to-weight ratio. Running is a power sport, and it's all about improving that power!
And we had tons of our favorite topics to discuss! Other topics: getting used to on-course nutrition options, the emotional process of getting to start lines, vibes-based earrings, David's up-and-down crash recovery, a new study on fasting metabolism, 3D-printed shoes winning the Boston Marathon, the new UTMB and HOKA partnership, an international doping scandal, a cool study on e-sports training, Dan Quinn's approach to coaching, a new menstrual cycle study, and hot takes.
Thank you for helping us with the courage to do scary things! We love you all! HUZZAH!

203. Canyons 100k Pre-Race, Improving Power, Perils of Energy Availability Cycling, Wild Shoe Tech, and Crash Recovery!

We got extremely hyped watching the Boston Marathon before recording this amazing episode! The main training topic was a new study connecting carb intake during exercise to reduced central fatigue, leading to the researchers theorizing a link between "excess" carbs and improved neuromuscular function. The study protocol was weird and wild! Does this mean we should consume mid-podcast gels to improve joke performance? We promise to edit out the slurps.
We also answered an incredible question on balancing a focus on the process with the competitive fire to race at the limits. The answer gets to the core of why we think athletics can be such a powerful stimulus for personal growth.
And this episode was one of our most fun recordings ever, full of fascinating topics! Other topics: Megan reaching the taper for the Canyons 100k, the USA Olympic jersey scandal, updates from David's crash, the perils of dictation apps, 6 instant reactions from the Boston Marathon, an intriguing study on ketones and cognitive performance, Parker Valby's cross training schedule and what it means for training theory, mental health and performance, and more controversies in track. 
Megan even made what she called a "David statement" (definition: excessively bold and likely wrong), which is how you know this one gets spicy. We love you all! Huzzah!
