First workout back

Yesterday I got beat up had a massage.  I felt much, much better this morning, enough that I went out after work for 2.5 miles of run/walk.  Over the last 6 weeks, I have not done any runs over 3 miles....  I have physical therapy tomorrow and I'd really like to be able to add in some mileage again (maybe next week?).  My goal 10K is this weekend, needless to say I will not be racing!
