I have been pondering over a recent discussion on here and the suggestion that most of us are just doing it by the clock and for that reason won't achieve our goal of 5k.
Our organised C25k group meet at a local running track, we then run on the roads and through a park and back. The exact route changes depending on where we are in the program, our W6 D1 on Tuesday measured 4k.
The route previously used for the graduation run is definitely 5k , I would feel cheated if it was anything less. Surely we all want to achieve our 5k, just how long that run takes us is irrelevant. The structured NHS program simply prepares us to be able to reach that end goal.
