Mind over matter

I went running this morning. It's damp and a bit blustery so not ideal conditions but I did 3.2km in 18m10s. That works out at 5.7mins/km which isn't too bad. Lets put it this way, if I could run 5km in 25 minutes I would be delighted at this point. The bad news is that I am doing it in almost continual pain. It became very noticeable around the 8 minute mark and was bad enough to get me very close to giving up. As it was i decided to keep going and it didn't get any worse so I guess I just have to accept that that is the price of staying in reasonable shape.
