I ride to work twice a week right now. 23 miles each way. And once in the morning on the weekend. Which will either be a 30 mile ride or a 46 mile ride. Depending on the amount of time I have.

The only thing I bring with me for these rides is water. 3 normal sized bottles. I usually do these rides on an empty stomach and drink some BCAA's 30 minutes before the ride. I only get hungry on the morning 46 mile ride. I only get hungry on the 30 mile ride if I ate light or trained hard the day before at the gym.

I want to start doing some loner rides. Hopefully 100+ miles. I want to do some 3-4 day 100+ mile a day tours as well. So I'm curious how much food does someone normally bring on a 100 mile ride. Or do you even bring food for a 60 mile ride? Basically, when does eating while riding become "necessary."
