In this episode of the NDURANZ Podcast, Alex and Dr. Tim Podlogar break down the fueling behind the sub-2 marathon, looking at how much carbohydrate the top athletes reportedly used and whether 70g, 100g, or even 120g of carbs per hour can make a real difference.

They also explain why marathon fueling starts before race day, how carb loading and low-fiber eating can help, and what everyday runners can learn from elite marathoners without blindly copying them.
