A cliched photo and one I have done a few times before. I tried a shot of the Tower from the other side of the river but it didn't seem to be working, so I kept on going and ended up snapping for a bit before heading off to check into my hotel.
3 good things:
1 - Arriving a tad early in London
2 - A great 8 mile run across London
3 - Unexpected dinner with a friend in Soho that evening
