I was suppose to go 4, but only had time for 3. My cousin Tina called me just as I was going out the door. We haven't talked in a LONG time, so 1 hour and 20 minutes later I told her I HAD to go since the gym was closing in 35 minutes!! I could care less that I only went 3 instead of 4 since I know this week is about staying loose and not about cardiovascular training.
Also, I have decided to take ibuprofen everyday between now and the marathon to hopefully help out with my back.
