Thanks very much for your best wishes. I don't weigh much more, I barely tip the scale at 72kg and that was before I started the tour. Being my first tour, I suppose I was always going to be heavy until I learned what I could do without. I also no no different in terms of weight, so in some respects this is my 'norm'. Wheels were handmade in England for me (700cc, Rigida Sputnik rims, combination of Sapim Race and Strong spokes with Shimano LH hubs and a Shimano SLX 9 speed casette).
Other than writing a blog, I have not done much with the cycling detail. The cycling is really a means to an end for me - the main emphasis is birdwatching. I rarely cycle the 'usual north/route, so don't bump into many other cyclists. I had never heard of CGOAB until you mentioned it, but thanks for the info - looks very useful!
