Did I mess up?

I've completed three half marathons and I'm now registered to do a full on April 3rd...I had my LBL Dec 10th so 6 miles is as far as I'm running right now.

I don't think there is no possible way to train to be able to run the full 26.2 but a walk/run plan will be
doable won't it? My goal is 6 hours or less (hopefully 5:59 or less so I can beat Meredith Viera's time in NYC )

Thoughts?

You should be able to get up to a 16 mile long run in the 9 weeks till the event. That will be enough to get you to the end with the run/walk. It will hurt and probably suck a little but you will finish. Good luck.

 I'm pretty sure it will suck a lot.  But it will be worth it :)

The last marathon I did a couple years ago, my longest run was 16 or 17 miles.  It wasn't a great marathon, but still finished in 5:30 - 5 minutes faster than the year before when I did 21.
