I hear what everyone is saying about Camelbaks. Among the front rando riders, I was the only one with a Camelbak. OTOH, I use it on every ride over 2 hours, so I'm very used to it. No discomfort on double centuries. It doesn't weigh 4 pounds. When it's full it weighs more than that, but why would I fill it? 40-50 oz. will get me to the next control, when it's almost empty and weighs essentially nothing. The good thing is that I use it. I can see that I drink a lot more often than guys with water bottles. I had to pee twice on the 200k, just right. But sometimes I do fill it. I fill it for the first 60 miles of Ramrod, for instance, so I don't have to stop before the Park entrance. I use the simple Camelbak, with no cargo attachments to tempt me.
My fueling strategy at this time is to use liquid food, a carb and protein homebrew. I know that will work for up to 400k and probably beyond, though I can see wanting a burger and fries or maybe some cold pop tarts. So food takes up one water bottle cage, leaving one one for plain water. Not enough. Don't like the jersey pocket thing. Too loose for me. I'm a tight kind of guy.
I see there are 30 oz. bottles available now. I could dial back the strength of my food concoction to just 50 miles worth, and have a second 30 oz. bottle. That would be good for 50 miles for sure. Anyone use big bottles like that?
What do you rando folks get when your mouth is tired of the usual stuff and you're near a store or fast food place?
