Ran the final w9r3 today - hurray! Very cold, but fortunately only a few light snow flurries, so Somehow it felt a lot better than w9r2 a couple of days ago, and without trying I was a little [not a lot] quicker as I had to take a detour to finish my warm-down walk before getting back home.
My aim is to consolidate this using all the advice given here [thanks icklegui ] then work towards 5k and a parkrun sometime.
