Down the river from Blackfriars

I'm out partying later so decide to get a good run in early.  I plan to run from Catford to work but get the wrong train and decide to run down the river from Blackfriars.

I know the river path well from my time in the City.  I now know the Canary Wharf end of the path.  It's hot and I am soon pretty sweaty.

I notice the Olympic rings are still on Tower Bridge before turning to run down the canals and to the docks.
