At 70 kilos, when I do more than one pass, I try for 250 calories/hour, though I usually can't manage that much, climbing robbing the stomach of blood as it does. I have maltodextrin and a little whey protein in one bottle, plain water in the other, or in a Camelbak on long rides. I've seen quite a few riders with stomach issues on long hard rides, had them myself, hence my current practice.
