I'm thinking a small camelbak with and extra change of clothes and using the support stations should work.
I would'nt wear a camelbak for 550km.
I get the clothes thing though.
There is one of those Devold outlet stores on route.
I did a day ride recently were I started too warm, was about right over the Mountains, and then again when the sun set. I would have preferred to have suffered a little cold, and then been more comfortable in the Valleys. But mentally it was Nice knowing I was overdressed. I also found it mentally comforting to keep my bidons full even when I know I can refill soon.
