I've only done one marathon and that was back when I was in the Marine Corps stationed at Hawaii. I did the Honolulu Marathon in 2001 and my time was 3:09. Yes, I have an excuse! I ran the first 10miles in 1hr exactly which was way too fast for me and had nothing left towards the end. Actually by the half way point 13.1 miles I felt like I've been hit my a truck, lol! I some how managed to drag my ass the rest of the way finishing in said time...I like 5k's better ha-ha!
