Overshooting The Plan

I must have forgotten how to count. My brain cells are either disappearing slowly due to age or oxygen debt. The joints and muscles of my lower extremities are still sore from Saturday’s 14 miler so I decided to do a 5 minute run / 1 minute walk workout so as not to aggravate my right ankle which hasn’t fully recovered. After all I have no business running 14 miles on that ankle anymore but I still did it. The plan today was to do 10 repetitions and that would have given me a whole hour of running and walking. Well along the way I miscounted the number of repetitions even though my GPS watch was giving me a countdown (I have it set at 60 repeats in case I would ever run a marathon again… NOT!). When I finally thought I did 10 repetitions and clicked my watch off, I found out that instead of running for an hour, I really ran for an hour and 12 minutes, which was 2 more repeats than I intended. Jeepers! How difficult is it to count to 10?! Today I lost my mind and couldn’t do it.
