10 AM 2 hour run. Ran out to Island Pond Road into Derry which eventually took me out to Kilrea Rd at about the 4.75 mile mark of the Prep course. At exactly 1 hour turned around and finished in 1:57:30. Jogged around for 2 1/2 minutes to make it 2 hours even. The course is hilly both out and back but probably less hilly coming in. 16 miles.
