Here is the idea being floated - very little time to act on this:

"It has been proposed that this year a single ride of London Critical Mass should start at its usual South Bank meeting place on May 1st at 11am, then proceed, via some of the earlier events on the day, before meeting up with the main event in Central London, which is scheduled to start at 2pm."

The ride will tie into events already happening on Mayday around London.... of course this wont be any good unless as many people as possible participate, that means you!

Preliminary planning is taking place on the London CM discussion list, to join the list and help plan send a blank email from the email account you want subscribed to  cm-london-subscribe@lists.riseup.net
