I took Laura's advice and varied my route this week. For one run I went the opposite way round to usual. Today I ventured in a different direction which included a grass footpath, unlit, at around 6.30 am!!
I'm now building up a record of runs on Runkeeper and although I'm not trying to go faster, the records show I'm continually getting faster - ever so slightly.
Most of my early weeks were on my treadmill. But as the runs have got longer, and the treadmill is so boring, I'm pleased to have ventured out more (even though I've probably signigantly added to the pavement potholes of East Yorkshire!!)
A colleague runs around 8 miles each lunchtime and admits to hating it. I can't honestly admit to enjoying the actual running. But as my colleague said, the real enjoyment is in the sense of achievement; knowing it's done and that you're on a mission to look after yourself better. And I certainly feel less guilty about the odd wine or beer at the weekend!
