I promised to report back on progress after visit to physio to try and sort out stiff legs.
Well, the first results were a bit ropey as a side effect of his manipulations was to unblock a constipation problem he said was also due to lower spine posture. (Not there and then BTW!)
The upshot was that my next two runs had to be abandoned after 10 minutes to return home.
However, Sunday morning, I tackled my 6 km hilly run and knocked 2 and a half minutes off my PB. Legs felt better and I could concentrate more on breathing and hip & shoulder posture.
So I’ll keep up the exercises and see him again next week.
