Honestly, I was not on solid ground when going for a nutrition strategy for my 24-hour ride this summer. My options were either my normal Ironman-distance race nutrition which is mainly gels or my normal training nutrition which is mainly bread with peanut butter, honey and banana. Or the third option which is something in between. I went for more training like nutrition and luckily it worked out very well, with enough energy and without stomach issues.
I am also lucky enough for work with PrecisionHydration which have one awesome Sports Scientists in Abby Coleman. She broke down my nutrition intake and got some interesting numbers. Read more about it in the blogpost on PrecisionHydration. Spoiler alert. 10000 kcal was a slight exaggeration but 9934 kcal is still an impressive amount to eat while riding 😀
