Timing of fueling

Assume that you are going to do some sort of fueling for a shortish trainer ride, say about 1h. I know many people, including myself, don’t always fuel a workout like this. But let’s assume you do. How much before the start of the workout ‘counts’ and also, how late in the workout makes a difference? For example, lets say I were to eat a bar or gel 15min before I started could that be all I do? How about a snack an hour before?
