I rode in my first race ever this last weekend and am totally hooked. I noticed watching all the expert racers that they don't seem to carry a lot of stuff with them. I on the other hand was wearing my Camelback, had an extra tube, tools, even my car keys. Okay, so I got a few kinks to work out.
What should I carry with me besides water and nutritional type stuff? I assume most racers carry the least possible items, right? Any advice for someone new to this?
