Foolishly headed to Regents Park only to discover that the outer loop was blocked about 400m from Winfield House and I had to detour around. Should have realised thatDonald was in town for NATO. It was interesting that there was a noticable temperature drop when I emerged from Great Portland St and crossed the road into the park, a distance of 50m or so.

Along the Thames path to Tower bridge and back the other side. The section of path under London bridge was taped off, on the north side, but open on the south side. That and the buses still parked on the bridge.
