Another newbie here -- but I've been scouring the threads and haven't found much for those who want/need to carry along some fluids and not just count on the water/Powerade stops.

Anyway, I've been training all summer in sunny Florida with an old 70 oz Camelbak Rogue backpack -- and on long runs a 32 oz Camelbak Catalyst waistpak, too! Recently I tried out a midsize 50 oz Hydrobak that's a little lower profile and lighter. I tried carrying a 16 or 20 oz bottle, but the sloshing just really bugs me for some reason.

I know there will be water/Powerade stops ever 2ish miles and VA/DC definitely won't be as hot and humid next Sunday as FL has been all summer(!), but I've gotten used to having my own water w/me for whenever I want/need a little.

So, whaddya think? See many Camelbaks on the MCM course?
