4 miles for H&S

I joined a gym earlier in the month.  I knew I needed a good way to work off stress.   It is too cold up here in Maine, even though it has been a mild winter so far.  I pulled a  hamstring muscle about eight months ago, so I walked a half mile and then jogged a half mile until I did four miles.  I am hoping to rehab it to be able to do some 5 K's this summer and maybe even a 10K.  I am wondering if I wear a pedometer at work does that count?  I was thinking about that all day, as I seemed to have been walking all day.   Go H&S!
