Race against myself

Workout #2 for week 4 of my St. Louis Marathon training plan.  I did a 5k at race pace on the treadmill.  I wanted to finish around 20 minutes, but fell short by 30 seconds.  Not too bad for the off season.  I have not training at that intensity since October.  So, I am please with my results today, and hope that It helps my marathon training.  Next weekend I am back to the long run.  I am not looking forward to 18 mile.
