Long run - 20 miles @ 8:28 pace. Ran Creve Couer lake to St. Charles river front on Katy. Felt great on the run, used 3 gels, 1 bottle Heed, plus some Gatorade. Picked up the pace a little at mile 17. Last mile the foot was starting to hurt pretty bad, so last half mile was junk! Overall, great last long run before the marathon.
