I don't drink a lot of water during my runs; I've found it can make me cramp up, lose my rhythm, or get that uncomfortable "sloshy" sensation in my stomach. But a couple of hot, exhausting runs this past summer were enough to make me change my habits. Stopping for water on tough runs gave me a quick break, some hydration, and a refresher to help me gut out those last few miles. It helps to plan a running route through a park or area with a couple of drinking fountains; you can also carry a small bottle for sipping when you need it. And if you plan to stop for water during a race, it's best to rehydrate during your training runs to help your body acclimate to the habit. (You and your stomach will thank us on race day.)
