175. Running Controversies, Chicago Marathon Stories, and Heart Rate Changes!
We brought some A+ brain energy and some C+ heart efficiency to this awesome episode! The main topics involved the extremely eventful weeks in the running world. On the joyous side, the Chicago Marathon was a race for the history books, with a new world record and blazing fast times from US runners. We celebrate the incredible Molly Seidel, plus talk about body image, fueling, rest days, training volume, and more. On the less joyous side, we discuss a controversy from a brand's social media post about the Boston Marathon. You know the one. And if you don't, get ready for a wild ride into the intersection of marketing, social media, and unintended consequences. We break it down, challenge each other, and hopefully come to a loving conclusion... After Megan was 100% right, of course.
And this episode was jam-packed with a mix of both important and irreverent discussions! Topics: last week's heart health setback, our hope for the future, training partners, protein intake, starting strength work, the cancellation of the Twin Cities Marathon due to heat and what that means for the future, abnormal heart rate responses, how to manage inflammation, and a listener corner email that will BLOW YOUR MIND.

173. Grindstone 100k Lessons, Jim Walmsley's Training, and Marathon World Record!
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 training, distilling some lessons from last week's interview. He gave us so many good nuggets, from weekly mileage to workout structure to season distribution, and we savor those tasty, tasty nuggets. Now we just need to convince Jim to let us co-write "The Walmsley Method."
All-in-all, this might have been the most fun we have ever had recording an episode! Other topics: the best sports story of the year, why we want to be like cyclist Sepp Kuss, a new study on training intensity in top cyclists, the $500 shoes from Adidas that were just used to set the road marathon world record, why that record makes us feel a bit queasy (with some unexpected tangents about economic theory), thoughts on caffeine intake via a new study on sleep impacts, and hot takes.
