Just wanted to thank all those who gave me advice and support.  I ended up deciding to run the whole way, taking breaks as I needed.  I set myself 3 goals: A) Under 2:20xx, B) Under 2:30x and C) Under 2:36:39 (last year's time on the same course).

 

I knew that miles 5-10 would be hilly (Flying Pig), so decided to go a little faster for the first 5 miles, as I knew I would lose time on miles 5-10.  This strategy seemed to work well for this race, as I did end up needing to walk up parts of 2 hills.  I also took my own water, so that I could fuel as I wanted, so I didn't stop at any of the water stations (until around mile 10, where I took a little gatorade).  The last 3 miles of the race are pretty much downhill, and I flew down these hills, with 2 of my fastest miles being miles 11 & 12.

 

My final time was: 2:17:25, my second fastest half marathon ever, and the fastest I've run since October 2011!

That is most awesome. Congratulations, I'm very happy for you!

And thanks for coming back here and letting us know how it went!

Thanks for following up.  I didn't post when you asked for advice because my 2 cents were already covered by others.  I'm glad you decided to run the whole thing and ended up exceeding your "A" goal by quite a bit!  Congratulations!

Excellent job!!

Thanks everyone!
