Paid Ride Marshals and Leaders Required, SW London a priority

Still asking, did anyone see any marketing for the Cycling Superhighway rides?

Nope. And also received the leaflet yesterday (East London).

• If there is not enough demand for the ride, you will receive an email letting you know that the ride has been cancelled and where possible, details of alternative ride dates and times.*
  
  
  

That's not very optimistic. More about cancelling than about the actual guided ride.
