The physio says my back is strong enough for me to start running again, so today I went to to Run 4 It in Dundee, was assessed by a charming almost-graduate in Sports Science, and have new shoes. Luckily the shocking pink ones were less suitable than the cool blues. They felt fine on the treadmill (actually, nothing felt fine on the treadmill - my first time using one and it was not an elegant performance) but I think they will be good.
I'm going to work on strength and stretch this week, then next Saturday, Husband and I will start again at W1R1. This time, this time I'll get there.
