I was pretty impressed to hear in the breaking 2 documentary that Zersenay Tadese had never drank water during a run. I highly doubt that the original poster is an "elite runner," an even if he is an "elite" American runner there is no doubt that his half marathon PR is far slower than 58:23. Focus on running and don't waste time thinking about drinking water. Also, thanks to Johnny 5 that thread on fanny packs is simply brilliant.
