Kimmy, most of the time if I'm running long I will take a short walk break while I drink. You don't need to walk for very long, just long enough to take a couple of swallows and off you go again. Unless you're racing and in a position to gain or lose a placing there is no need to run and drink, IMHO. When I train I figure in walk rests for 1 min every 20 min anyway, so I use these to drink.
