London 10k Winter Run

I do a lot of runs.
I particularly enjoy doing 10k's in Central London when the traffic is shut off. 
It's great to run pass such landmarks as Big Ben, Houses of Parliament, London Eye, Tower of London, St. Pauls Cathedral etc. 
No other City in the World can boast such historic Landmarks.
What is great is that London is my home City, and to know this is on my doorstep whilst people travel from all over the World for these runs meeks me feel really proud.
Todays run was a new one. It's the first to be organized in Winter.
It sure was cold!!
