FOR TODAY'S WORKOUT, RUN 5-6 MILES: Stretching can help, but it can also hurt. The wrong type of stretching is actually the third leading cause of runners' injuries. (Running too much mileage and excessive speedwork rank first and second.) Never stretch right before or right after running. The best times are when you're relaxed and warmed up from your day's activities, either in the evenings or throughout the day as you have time.
