Ran with Phil. Overall it was a great run, but I had GI issues the last few miles. I made a mistake bypassing the porta-potties at Deep Wells. I should have taken a "break" there. Instead I tried to hold it and finish, but I ended up cramping badly after we got over Shell Hill. I had to walk a few times in the last mile due to intestinal cramps, but at least I got to the porta-potties at the Steeplechase ok. Next time I'll get up earlier, drink a lot of water, and unload at home first.
