Callum Walker | Figuring It Out · Feb 10, 2026 · 13m · transcript

In 9 weeks time, I'm running the Paris Marathon.

But I'm doing it different to how 99.9% of people would normally run a marathon. I'm doing it on a ketogenic diet without any carbohydrate whatsoever.

Is this possible? Perhaps.

Is it dangerous? Could be.

But... In the first entry of The Carb Free Marathon Diaries... I reveal the science behind why this theoretically should be possible and exactly how I'm going to be running a marathon without any carbs whatsoever.

Enjoy.
