You would normally take only water in this short a race. Though something like Gatorade won't hurt, your body doesn't really have enough time to digest and make use of the nutrients during the race. It may be some benefit to take sports drink or energy gel shortly before the race. Just watch how much you take so you don't get an upset stomach. I personally don't have a preference on gels or drinks.
Thanks guys. I'll forget about the ADES, etc. and stick to my water.
I carry a water bottle when I train and race to combat dry mouth and for comfort mostly. When I race, it is rare that I find a water station when I want one so the bottle has become my security blanket sort of. I may dump it for this race just to keep my hand free.
