Zoom Zoom - so that hydration belt doesn't bounce too much for you? Or the bottle doesn't leak being on it's side like that?

I wish you'd posted this earlier! I just purchased a Nathan belt that holds a water bottle on an angle. It seemed to sit the best on my back in the store - but until I fill it with water, it's kind of hard to tell. Since I do like gels when running, I also purchased one of those clip on small bottles you mention. I like the Amphipod ones because they have a wide mouth (for a tiny bottle) which should make them easier to clean. I also like that I can suspend them upside down for quicker gel access!

If this version doesn't work for me, I'll try the one you recommended next.
