This is my first post. May I ask this is not restricted to road bikes only is it? I have a MTB that I have recently bought, and I am not very fast so I don't think I can do the distance with a very fast pace.
Maybe I can do about 10 MPH because I have not done more than 3 miles before.
everyone is invited to ride but please bear in mind that the pace is a little faster outside central london and the ride can take up to 3-4 hours depending on stoppages for punctures and food etc.
