I'm wondering, has anyone done a century with a CamelBak? Also, should you take in carbs every 30 or 45 minutes--stuff like Carb-boom, Cliff shots, or more substantial chewy fun food?

I might do a hilly 100 in October provided my knee can handle it. I can comfortably ride 45 miles now and I've been at it for about a month I guess. I'm still trying to figure out my on the bike eating schedule though. Any suggestion?
