After 85 miles I barely even want my Clif Bars in my jersey pockets, much less 9 pounds of sweaty backpack.
Not sure of the weather where the OP is riding but the CB makes me sweat where it sits. We do a training ride, 40 miles with 5k of climbing. Sometimes I take the CB cause there is no water up on the mtn course and it gets HOT! I'm not much of a dripper so without out it, I sweat a bit. With it, my back is soaked.
At the end of the 40 miles, my arms are fatigued from carrying the 75 oz CB. I had tiny triceps before I started using the CB. But I'd wouldn't use it on a century, simply for the final 30 miles.
