Our minds were blown by the Boston Marathon right before recording this great episode! The main topic was a new study on the Puma R3 super-shoe, conducted by a top researcher. It showed a shocking 3% improvement in running economy relative to the previous generation of super-shoes, with a universally positive response among study participants.

We discuss the evolution of the tech, how it was made with the help of optimization algorithms, and what might come next. Running may never be the same, and we don't think people have realized it yet.

We also had some instant reactions to the Boston Marathon! That included Jess McClain running a 2:22 for top American while working a busy job and training with lower volume. We break down some of her training!

And this one was full of amazing topics! Other topics: Boston Marathon thoughts, how carbs are changing the dynamics of road marathons, nose strips, the awesome Coffee Club podcast, an incredible article in Outside Mag by Devin Kelly, Strava's acquisition of AI coaching app Runna, a hilarious post-exercise cooling study, a quick-hitter news rundown, fatigue resistance efforts, how time on feet in your job may change training, resting heart rate variation among people, downhill form, and creatine for endurance athletes.

This one was so fun! Thank you so much for being here.

Let's go girls,
