When you're running, it's important to stay hydrated, since you can end up sweating a lot. Waistpacks that hold water bottles [1] are great for biking and hiking when I need to have my hands free, but when I'm running, I love the easy access of a hand held water bottle.

Check out this one made by Nathan. This is the 2008 QuickDraw Plus Hydration Bottle [2]. It's got padded and adjustable straps so you can secure it snugly and comfortably to your hand. The water bottle can hold up to 22 oz. of water and there's a zippered pouch to keep small essentials like keys, tissues or a cell phone.

Another thing that's great about holding a water bottle in your hand is that since it's filled with water, it acts as a weight. I switch back and forth between my left and right hand every minute or so to work both arms equally.

The pink version shown here has a tiny pink ribbon on it so you can show your support for breast cancer awareness [3]. Order this hydration bottle [4] ($16.19) from BikeSomWhere.com.
