ATTQOTD: I carry my own bottle, but need to refill it from water tables. My approach is: upon sight of water tables; twist off bottle cap and hold cap in teeth, retrieve Nuun tab and drop into bottle; pass all Powerade tables by continuing through center of course, walking or running depending on what the crowd's doing; pass most water tables while beginning to work my way left or right, walking; grab one cup from 2nd to last table, pinch and pour into bottle while walking; grab second cup, pinch and pour into bottle; if hot, grab third cup from end of last table and hang onto it until past tables, then carefully, so as not to splash anyone else, pour over head and back of neck; twist bottle cap back on and resume race, thanking volunteers loudly. All cups get tossed into garbage cans or off to side of course, depending on situation (cans are often overflowing by the time I get to them). It sounds like a lot, but I've got it down to a science at this point, lol!
