One additional thing… you might think about investing in a sports watch (Target has a pretty inexpensive Timex Ironman that does intervals, if you want to go that route.) One thing I found at my first race is that I knew nothing about pacing. Figure out what your race “plan” is (what pace you plan to run) and be careful not to start out too fast. It’s REALLY easy to do with the adrenaline going and running with all those people. Figure out what time you should reach each mile marker and be sure to save something for the end.

Also, generally, start integrating a long run (maybe five or six miles for you) once a week into your routine, and run it at a moderate pace. Save the faster stuff for the shorter runs.

Great job! Good luck with your training!
