Can't wait. I have ran this race twice before once in 2005 when I was a 20 a day smoker, once in 2009 when I was 12 months post stopping and been running for 6 months. Managed 2hrs 20ish on both occasions.
Now with a few marathon's under my belt, a PB of 1-54 im coming back to kick that sting in the tail in to touch. However having just completed a trail marathon, I think anything under 2hrs would be happy me. 
This is a great event, and well worth the money. Manged to talk about 7 members from our club to join us.
