A gentle 'social' roll round Leigh Woods or Ashton Court. 
One or 2 loops with a stop for a cuppa etc in Leigh Woods - A/C.
These sessions are intended to help you 'try mtb' or improve your technique if you're already hooked 😃

Bring a serviceable bike, helmet etc.

Let us know if you are a complete beginner; we can go through the basics, and go through what you can expect in the session (there's nothing extreme !)
