We had a ridiculous amount of fun recording this episode! The main science topic was on a new pre-print study on post-exercise ketones, showing higher carb storage and lower glycemia in athletes taking them.

Is it possible that high carb has a special interaction with post-exercise ketones that might be at the heart of recent performances? It's uncertain. We just take them because we like the taste of robot butt.

We also had a big breakdown of the cost of high-carb fueling. Megan did calculations on the price per gram of carbohydrates of different fueling sources, from gels to drink to at-home creations. It seems like some companies are giving you amazing deals, and some... are not. We name names.

And this one was full of great topics! Other topics: heat training, a promo for the Core 2 sensor, David's post-race knee pain and the uncertainty of being an athlete, total energy expenditure during and after ultras, thoughts on the Cocodona 250, Stephanie Case's remarkable performance at Ultra Trail Snowdonia, plus a Q+A on depletion runs and a how-to on uphill treadmill.

May your pantry be full of carbs and your secret drawer be full of SECRET hair.

We love you all! Huzzah!
