Brady Holmer is back for his third appearance, which officially makes him the most tenured guest in Out and Back history. He's a week out from Grandma's Marathon, coming off a stress injury and a training block built around high bike volume, durability workouts, and progression long runs in the Texas heat. The conversation covers a lot of ground: what the research actually says about high carb fueling (and where the evidence gets murky), why the crossover point matters more than oxidation rates, gel selection and why he's cycling between multiple products, a new ketone IQ study showing a 15% boost in EPO production post-exercise, and what Nomeo is actually doing in the body. Then Jacob admits he spent race night at the New York Half taking Advil PM every hour hoping to knock out, and Brady walks through what the research says about sleep before races -- including why trying harder to fall asleep is the worst thing you can do.

David Roche -- ultra marathoner, elite running coach, and what Rory's calling the godfather of the high carb revolution -- joins the Out and Back for episode 40. He started as a running back at Columbia, spent years coaching before ever being competitive himself, and broke the Leadville 100 course record in 2024 (and again in 2025!) largely by stress-testing the same principles he'd been building with his athletes. The conversation covers a lot of ground: how he thinks about carb intake across different race distances, why he separates hydration from fueling, the case for uphill treadmill threshold work, what unites his coaching across trail, road, and ultra, and why he keeps looking to cycling for answers the running world is slow to ask.
