An update for those concerned about how my back is progressing.

Went out and did some indoor climbing last night. Things felt a bit tight to start with but by the end of the evening I was almost as good (or bad) as normal.

Today I took off for a short ride of around 90 minutes in the Port Hills to the east of Christchurch. I was pretty happy with how I went and even felt good enough to try out a bit of downhill track which I hadn't ridden before . Got home and although my back was a little tender it is certainly pretty close to being normal - though after mowing the lawn I did need to sit and rest my back for an hour or so!

Anyway, all things considered, it's looking very hopeful as I can now at least do the things that I want to and with a little more time should be able to do it with no residual pain occurring.

Thanks for those who offered condolences - they were all appreciated.
