Changed it completely by going for a run after work yesterday instead of the early morning. I also went back to my old route and actually ran past the half way point to those farm buildings in the distance that I was aiming for all that time ago. The wind was against me on the way back so it was a combination of walk/run (mostly walking!). 4.67km in 50 minutes according to Runkeeper, but 4.47 in 47.59 with my Forerunner 10 because the GPS didn't kick in until I was well into my 5 minute warm up. That will teach me not to put it outside while I get ready.
