Oh, yes, RAAM is still being done. I have at least three friends racing in it this year, and my girlfriend is on the crew for one of them (8-person team, in this case).

funlvnman, this ride is supported, so chasem won't have to carry everything. There are rest stops along the way.

My own experience with longer rides like this has been that since I cannot tolerate Gator-Ade any more, I carry mix for my drink of choice (in my case, Hammer Nutrition's HEED or Perpetuem, depending on distance and output level). That way, I get water at the rest stops, toss in the pre-measured mix, shake the bottle, and be on my way. If I have a personal support vehicle and person, I get the luxury of simply trading bottles.

I tend to prefer bottles to hydration bladders, as it's easier for me to monitor how much I'm drinking that way. On long events like RAIN, I may have a small hydration pack loaded so that I have water to drink should I use more that I'm carrying in bottles between stops for some reason.
