I ran Philly on Sunday. It was my first marathon so I don't have too much to compare it to but there were some small problems that have already been mentioned. The bag drop was a disaster but it was resolved. Nobody knew where this was. When I finally found it I heard a warning that there was 10 minutes to the start and a line of about 200 people waiting to drop their bags. Luckily someone organized piles on the sidewalk based upon your bib number. This wasn't the most secure way to check your bag but it worked.
The mile splits were off at the 3rd mile but it could have been the 5k mark. The only problem is that the sign mentioned it was the 3rd mile. I read about the confusion regarging the mile markers at miles 11 and 12 where the 1/2 and full matathoners merged. This wasn't a problem for me and anyone who has half a brain could figure out which marker was for which race.
Overall I think it was a great race. I didn't have some of the trouble that the others who were running 3:00 or more probably encountered but I hope this doesn't discourage people from running Philly next year. I'll be back and hope to improve my time.
