During or after a ride of that length I will usually have cake and coffee at least once, maybe twice, before the 35 mile mark. More then twice makes it a really good 35 mile ride!
I think technically at that stage, it becomes a tour....
Porridge or toast for breakfast. Carry some snack food you can easily eat along the way. I like chocolate raisins. If I were riding that distance, I'd probably want a cafe stop for tea and cake, if that's not practical, carry something more substantial, like a sandwich. Have some muesli bars or flapjacks in reserve too.
A lot depends on how long you expect to take. For some, that's a couple of hours of high intensity effort, for others it's an all day pootle. The longer you're going to take, I think, the more you need to think about 'meals', as opposed to bloodsugar sustaining snacks.
Drink plenty of water, or dilute squash (which can be more refreshing, and I think gives a psychological boost due to sweetness.)
