I think I just spotted (and was spotted) by Clarion and Butterfly Adam and Rebecca (not of this parish), on Tamworth Lane, near Mitcham Eastfield station. I was inspecting my GPS and trying to work out exactly which turning to make, when two brightly lit cyclists came around the corner towards and past me, at some speed, in the opposite direction that I was travelling, as I was wondering about traffic and the junction. Consequently, I didn't really have much chance to see who it was, and just heard a "Hi Tim" from a male and female voice as we passed each other.
Given the location, Clarion and Butterfly are the most likely people, since of the few people who may recognise me in a YACF jersey, they're about the only ones who'd expect to see me around there!
