A couple of things I noticed were full protective gear (Helmets, spine protectors) and something I'd never seen before, leather pouches attached to the saddles that appeared to be survival kit. On account of a certain amount of physical frailty I do have basic survival kit in my back pack hoping it never as to be used.
Also a few cyclists, none in lurid lycra, all riding sensibly.
Earlier this morning I had the 6 month interim telephone check with the lovely Jan, specialist oncology nurse, all good.
Friday 13th has been a good day.
