One bottle of liquid every hour? <-- if you want to pee each 15 mins, yes...
Drink zippis each 10 mins (or when you need it)... that way probably the water will last you like 2 to 3 hours maybe more, but IMO 1 bottle each hour is like an exaggeration unless you are in like AZ and is summer. At +-15 mph you have to drink zips not 1/3 of the bottle every time.
As for the food, just kind;a the same... split bars in pieces and eat a piece of whatever each 15 mins, alternate with water zippies and continue riding...
This way probably you wont stop unless you really need water or need to go to the bathroom.
Have you ever drove like for 600 miles stopping each 2 hours?? the trip took forever right? This is the same thing, if you stop you have to warm up again, get into the mood and stuff... Have a friend with prostate problems and darn we have to stop in every single restroom
after mile 60 was not funny because the ride was taking like too much. This is just my opinion ok? Long rides to me have like 4 stops more than that is just to make the ride way too long.
Good luck in your ride
