I do like how I feel post-run, though, because my skin is extra tight and I feel light on my feet.
Oh, and Zimmy, if you're not familiar with those food gels (Goo Packs, PowerGel, etc.), I highly recommend that you check them out. During a LONG run, I recommend that you down one of these about every 6 miles to best maintain your blood sugar levels for better sustained energy. Also, avoid the food gels that contain caffeine early in your runs. Caffeine will cause your body to shed its stored water much too quickly, therefore, resulting in dehydration come about mile 15. Avoid caffeine until about mile 18-20 because it will then be your saving grace to the finish line!
Good luck!
