As they give out bottles you should be fine to use theirs as you can carry the bottle for a few k and take on all you need. Smaller runs that give cups are a pain and I prefer to carry my own. However as book said if you want it then do it.
Start to analyse how much water you are consuming in training. I am always sceptical on whether runners really need the volume provided in a camelbak (depending on distance of course).
I think the great runs give out powerade at half way which I advise (if you are going to use it) then train with it first. It did not agree with me at all.
Last piece of hydration advice form me is to have some flat cola in your kit for after. You can stick your power drinks flat cola is the only way to go just dont guzzle it.
