Is it half or full??

On the drive in to work this morning I pondered my decision....yes it is decision day. I told myself that when I ended the half way point of my 16 week Marathon training that I would decide. Currently I am signed up to run the Rock 'n' Roll 1/2 Marathon on June 27th in Seattle. In February my training was going really well so I emailed the race registration people and they informed me that I could upgrade to the Full Marathon for $20.... So for the last few weeks I have gone back and forth...

Half or Full?? I KNOW that I can do a half marathon (And will prove it on May 17th)....but will my knee, mind and body hold up to a Full 26.2? I am 8 weeks into a Rookie training plan and feel AWESOME, but maybe my body likes mileage less than 20?? Maybe I should just try to run a half marathon as fast as I can?

As I walked in the heavy doors to my office building I was closely followed by Stan (a VP and awesome guy...we bonded at a beach BBQ I helped plan at his house July 07). I said "You caught me in my dorky backpack." With a smile he said, "I am guessing that is your running gear, I see you and your co-workers out there a lot." Always happy to talk about running I replied, "Some of us are training to run the Rock 'n' Roll 1/2 and full marathon in June." Stan asked the question, "Which race are you going to do?" My Answer:

"I AM GOING TO DO THE FULL MARATHON!!!" I did not say it so excitedly to Stan, but in my mind I jumped for joy. I made up my mind, email is out to race directors and although it may be a TOTALLY ambitious goal I am going to tell them that my race time will be 3:40 (BQ). I will be a Marathoner in 1 month 3 weeks and 1 day..

The Course Map...We will drive it in the next few weeks so I can get an idea of what kind of topography I should train for.
