I even did the '07 Dallas Marathon. Finished first in my age group Males 43 yrs old, 3 months and 7 days from my zip code. Tell everyone you are doing it so they become interested and it helps keep you motivated. Sign up for the txt alerts at the expo. Best advice I got for running it was from a older gentleman who was intrigued and liked me because of my military background, he was a WWII vet. After grilling me about the training, asking about why I was doing it and how far it was he got to thinking. A couple weeks later he tells me, "You know I've been thinking about this marathon thing you are doing. If I was you I would just keep putting one foot in front of the another until you get to the end." Helped me handle it.
Cheers
