My fueling strategy for #MilanoMarathon looks like this:
Yesterday and today a drink mix.
Tomorrow: a drink mix and a bar.
Sunday: drink mix and two or three bars for breakfast.
Just before the start a gel and during the race a gel every five kilometers. From km 25 alternated with a caffeine gel.
If anyone has experience with the marathon and has a better alternative, I'd love to hear about it.
