I use a combination of bottles. Generally, its a handheld, or a one-bottle Nathan waistpack. When requiring more than 22 oz, then its both. For Mohican, I wore the waistpack. On the longest legs, I took a handheld too.<br><br>
I also have a two-bottle Nathan waistpack that I use mostly for 100M pacing. I used it for Laurel Highlands. It works fine, but I have not run too many event where I need it.<br><br>
I'm interested in one of the camelback-type systems. It seems the way to go for longer or unsupported runs.
