I've been a cyclist for a few years and really have the nutrition aspect nailed when I'm on my bike....but I started running a few months ago and find I have a big problem drinking water when I'm running because it gives me a terrible side stitch.

When I'm on a run of less than 5 miles I don't worry about it so much, and often put water in my mouth, drink a tiny bit and then spit the rest out. But lately my runs are getting longer, of course, and I'm going to HAVE to figure out how to hydrate! This weekend I have an 8 mile run scheduled and I hope to both drink water and try a goo (yeah, I'm optimistic if nothing else

How do all of you established runners drink without getting a side ache? Is there a technique I could try? Any hints are really appreciated!
