I've only run 7 miles one other time in my life. To date, it's the longest run. It sure feels different than 6 miles. I felt it more in my joints, and my legs were fatigued at the end. I've contemplated investing in a small hand-held waterbottle, and some Gu, for anything longer than 1 hour. I'd like to see if I can feel a difference.
Goal this coming week is to do yoga or P90X on all my rest days. I need it.
