I've modified my feeding process while on a long ride (50 miles +). I use to do gels and bars on the bike every hour and then would stop at around 30-40 miles and grab a sub and fill the water bottles. I've decided that the stops eat up too much time so have changed my approach so that I now eat in the saddle, only stopping for a quick fluid refill. I stuff an extra bottle of Gatorade in my back pocket and for calories load the pockets up with a mix of gels, Clif bars, fig bars, a couple of bananas and a couple of peanut butter sandwiches depending on the distance of the ride. This way I can stay moving.
My question is any suggestions on other things to eat while on the move. I've found that for me I need to consume 200-300 calories an hour for anything between 50-70 miles and for riders greater than 70 miles I need to consume 300-400 calories an hour to finish off with some strngth and energy.
