Though we will not force you, we recommend that you carry water or some form of energy drink with you on the run. If you don’t have a Camelbak or some sort of waist pack you can carry a water bottle in your hand. The benefits of a waist pack are zipper compartments that typically give you space to keep a hat and gloves in cold weather, car keys, lip balm, energy gels, etc. in addition to freeing your hands of a water bottle.
