I keep meaning to take up running, mostly to better my 2 mile run score for the National Guard. Right now I'm around the 18 minute mark, which isn't bad....but it's not anything to crow about either.

I have this tendency to like having things with me (see the preparedness thread and you'll see what I mean lol!) and running doesn't seem to lend itself to that. I'm not even sure where to carry my keys, much less water or anything else, and I'm exceedingly uncomfortable doing any activity without any water. I have a Camelpack, but it looks a little erm warmish for that kinda usage-age and heavy since since it's a three litre. Heck it gets a little hot to wear when I'm riding, and that isn't nearly as sweaty an activity!

So what do you guys carry with you when you run?
