I've been dying to sign up for a race this fall but ended up missing out on both the North Face 50 and the JFK 50. I finally decided to go to Rocky's home town and run the Philadelphia Marathon.
I would definitely prefer an ultramarathon or a trail race, but I think it'll be fun to try to run a fast marathon again. I set my marathon PR there in 2006 and it's a very fast course, so hopefully I can put up a good time even though I'm a slow ultramarathoner now.
So for now I'll do more speed work and temp workouts to get ready, and then it'll be back to the trails in 2009!
