I'm still working on getting ready for my first century ride on the 17th, and am confused to note that after long rides of 80 miles or more, I'm not hungry. I eat somehing every 20 miles -banana, granola bar, fruit roll up, power bar -depending on how i feel during the ride. Post ride I always fry up some eggs to feed the muscles... And that's it. Not hungry after that.

By contrast, after 40 or 50 mile rides I eat a LOT. I'm hungry for two days and pretty much graze all day.

Very confused by this. Any insight? I still feel good after my long rides, today was 85 miles with 4,434 feet of incline but I felt I could continue for another 15 miles just fine.
