We loved the London Critical Mass ride. It’s definitely one for every cyclists calendar!
We left from Waterloo and went around the city. It was great!

Report from the list:
The June mass started at about 1930, around the Imax, up to the Strand Tunnel, from Holborn to Oxford Street and a turn up Tottenham Court road, to proceed up to Camden to go down the next road to emerge beneath St Pancras to go east up Pentonville Road before heading south to Mount Pleasant, then back to Fleet Street, to go through the centre, Picadilly, etc., back down to Trafalgar Square then back East along the embankment, over the river at Blackfriars down to Tower Bridge. 5 minute wait while a DIESEL boat passed beneath. Then east a little on the cycle lane, looping back to go west along the embankment, turning up to trafalgar square again and finally to Buckingham Palace.
