My Garmin said I burned 1600 cal and usually tells me I'm burning something like 300-350 cal/hr on long rides (I assume so low because I'm slow).
Burning 300-350 cal/hour in that time is probably reasonable. So in 5 hours, you might have burned 1600 calories.
The general suggestion for long rides is to eat 500 calories for breakfast, then to consume half what you burn while you ride. So in your case, 500 calories + another 800 calories while you ride, which would be about 3 energy bars.
If you're fit, you can get away with less, but it is a good idea to carry those calories with you just in case you do need them.
