"Rides for everyone" - Barry Mason

"4. The agreed formal aims of Greenwich Cyclists are to:
· encourage more people to cycle
· improve conditions for cyclists
· raise the profile of cycling
Rides aren’t mentioned. But we do loads. For everyone." - Barry Mason
But who provides public liability and 3rd party insurance for such rides and who is going to collect money from the riders to pay for public liability and 3rd party insurance? Cycling UK know how to do this, but does anyone else know?
