Spotted...

Someone on a blue and white Fuji with (iirc) a green rim on the rear wheel, heading west along Kensington Road, at the westernmost end of Kensington Gardens, at around 8:30 this morning. I joined that road right behind you at that point but then turned right almost immediately onto Palace Green.

That's my mate Lawrence, his name is braincap on here I think. Doesn't post
