One of the things I love about running is the simplicity of it. You can participate and compete as a runner with next to nothing. There's no special equipment needed. But there are some things that can help.
If you run more than a few minutes, you get thirsty. Your body needs fluids. When my runs started to last more than an hour, I started looking into hydration systems. OK, that just means water bottles. I did not like the Camelbacks, which carry the water in a big bladder on your back and have a long straw to drink from. I thought the fanny packs would be to uncomfortable and would bounce around, but I found the Ultimate Direction two-bottle waist pack (that sounds better than fanny pack) to be just right, once I found the right tightness. It holds two 20 ounce bottles, has a pouch for extra clothes or food, and two small pouches on the waist band for gels, phone, or whatever. I wear this on all my long runs, and wore it at Inks Lake last summer so I could carry a flashlight and extra batteries.
