London CM meets on London’s South Bank, just under Waterloo Bridge. This convenient meeting point allows easy access to the National Film Theatre bar for pre-ride drinks. The ride goes around central London usually 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. The ride usually ends in a conveniently placed pub for more drinks. Anyone is free to join or leave the ride while it is taking place.
