2:33-ish :: 22 miles

Hit the wrong button on the watch and missed timing about 8/10s of a mile at 6:40 pace. I'll figure it out later. Good run overall. No problems with fueling. First 10 miles in 1:13 or so, 7:15 pace, then down to 6:35-6:45 pace for the second 10, and finally 6:25, and 6:18 for the last two miles. Started to feel tired around 18 miles, so there was a good 25 minutes of tough aerobic running at the end. Drank half-liter of GEF from miles 8 to 11, which seemed to work very well. Enough to get me through the majority of the run, but not so much as to prevent feeling gassed the last few miles.
