London CM meets at 6pm on the last Friday of each month on London's South Bank, just under Waterloo Bridge. Check the website to see a map showing where CM meets.
This meet up point is pretty central, chilled out and open, for pre-ride socialising and planning. There are a couple of bars / cafe's nearby for any cyclists looking for refreshments. The ride usually goes around central London taking in all the major tourist attractions such as Buckingham Palace, The Houses of Parliament and Piccadilly Circus. There is no set route, and the direction we move in is spontaneously chosen as we cycle. Anyone is free to join or leave the ride while it is taking place. The ride usually ends somewhere pretty central.
