Firstly. Sorry for not hearing about your health problems sooner as I have been rather busy of late and not finding the time to get on the reflector. Glad to read that you are improving and that the bypass goes well. At least you are still getting about.
So you won't want me or anyone else rushing you up a summit too fast for a while.
Secondly, I really need to get myself back in to some sort of routine so I can get back on the hills, really missing the leg ache, the cold, the wet, the fun, the views, etc. Everything is always ready to go with 30 minutes notice so I don't really have an excuse for myself and after reading your post I must get my finger oot!
Anyhoo, you take care and all the best from Cat and myself.
