There is only one that I have come across, City Runners:
They are a friendly bunch who meet in Bermondsey Square
every Tuesday for a 5km along the river or Sundays on the high street for a 10k. They run in groups dependant on speed (the medium and fast groups are pretty quick!) but don't seem to enter any races as a club yet. It's totally free.
I was attending before Christmas but have since been injured.
