So many athletes message me with the same lament: “I just can’t do high carb fueling without gut issues.”

I empathize with that feeling. In 2023, I raced the Canyons 100k, my first race over 50k (and my first race fully committing to high carb fueling). At mile 42, a gel came back up as soon as it went in, and my body proceeded to release the WRATH ON THE DEMONS BELOW on an innocent tree. The tree is still in therapy, and I uplift its mental health journey. Get the help you deserve, king!

Coming out of that race, I realized that the high-carb revolution needed to be paired with a revolution in how we think about gut training. For most people, it probably doesn’t feel natural to consume 75-120+ grams of carbs per hour, along with all of the hydration and electrolytes needed to ride the modern performance wave.

But what high-performance activity feels natural at first? Running definitely doesn't! If I took my first 10 or 100 runs as an indication of how the next 5,000 would go, I would have written myself off before I even got started.
