Critical Mass: taking to the streets!
Meet from 17:30 for an 18:00 depart, outside the Leeds City Museum on Millennium Square, on the last Friday of every month.
WHAT'S IS ALL ABOUT?
Critical Mass is often described as an 'unorganised coincidence'. It happens when a lot of cyclists happen to be in the same place at the same time and decide to cycle the same way together for a while.
