I got a hydration vest which is great for longer training runs (although the hose freezes on the colder winter runs, it's worked great the last few milder runs, but the first run with it, I got one drink, before it was unusable, might have to use warmer water on the cold days... or vodka), and some paddles and fins for the pool...
Does it have a cover over the hose? My camelback has a neoprene sleeve over the hose. And also has a foam cover over the bite valve for even more protection (when needed).
Also, take more frequent small sips, so that there is a constant stream of warmer liquid in the hose. I might need the vodka to get through my 100/100 runs today.
