Well, tonight I went out to run the 2 mile route backwards, in order to find out, once and for all, where that damned footpath comes out.
When I got to the entrance to mincing lake valley park I just decided to run on up the hill and this has been my most pleasant run yet.
I did find the footpath entrance, I saw a Delica up near Sainsburys and I ran six and a quarter miles in under an hour.
I guess that puts me in line for a 2 hour half marathon?
Without question I could have gone on and run the loop again tonight - I am much more confident now.
