The hospital appointment today has confirmed my forebodings.
No more running - when the man himself says 'well its your knee so I can't tell you not to but looking at the wear .....' you can't ignore the advice.
I'll probably get an VLM place now :<(
So its walking and swimming and learning to love the bike - but I don't actually have a bike at the moment. I shall wait until I get to the new job, when I can buy one through the 'bike to work' scheme and get Alistair Darling to cough up his share.
