I saw my orthopaedic surgeon two days ago for a follow up and was told I could resume cycling and other physical activities.  Yesterday I went for my first cycle ride in almost seven months and found it easy, though there was a little muscle fatigue towards the end. But cycling is now in the picture and I can build up my stamina in the coming weeks.  The Hadrian's route is not terribly strenuous so I am very happy with this development.

Here's that ride.
