OK, it took a few extra days since I was away but yesterday evening I finally did run three of week nine. That means I (somewhat unbelievably) completed the entire Couch-to-5k programme.
It was certainly a slower run - I'd been running 29m before the 5k came up - but in my defence it was very, very hot last night, I'd had four whole days off, and I was running off-road in rapidly darkening skies so I tneeded to be careful not to slip, trip or break an ankle.
Anyway - another few days off for me now as some colleagues and I are going for a weekend away. Next week I guess I'll consolidate with three thirty minute runs then maybe try moving on to the B210K.
Thanks so much to everyone here that's encouraged me directly or by just posting their progress. I am going to hang around and keep in touch.
