Once a upon a time when I averaged 200 miles a week (plus 2-3 yoga classes a week), I felt like I just couldn't eat enough to satiate me. I was hungry almost all the time, even when I purposely ate a good mixture of carbs and protein immediately after each ride.

I ultimately just ate a lot--big meals that included protein, carbs and healthy fats and lots of in-between-meal snacks. Because I neither gained nor lost weight, I assume that's what my body needed. I also made a point of staying well hydrated, which was almost as challenging, but thirst can be mistaken for hunger.

It was hard come fall/winter to curb that appetite, so just be forewarned that you may find yourself packing on a few pounds if and when your activity level drops.
