Most of my rides are on the Suncoast Trail which is almost perfectly
flat where I ride. It's all rural and there is no food nor restrooms
of any kind available along the trail. I can take a three mile round
road trip to a county park with restrooms if needed for more than the
occasional step_off_the_trail pee stops which the mostly unoccupied
nature of the trail allows. Back in the day when I did 70/80 mile
trips I used to take a small container of tuna/pasta salad for the
half way stops, but these days, I only need water.
