USMC marathon success

I enjoyed the marathon much more than the first time I ran it. It was much better organized this time and the people were nicer. Was aiming for 3:10 and ran 3:10:13. I'm definitely satisfied with that time as its just 2 weeks since my last two marathons. Plus, I started at near the back of the pack, about 20 minutes after the official race start. Lots of time spend trying to pass those people back there and lots of energy wasted in doing so. I probably wasn't able to run at a constant steady pace until around mile 12.
