Cutty Sark, Greenwich, next to the tunnel entrance.
Easy-paced, 3.5 hour ride, much on cycle paths. Out and back mostly on Thames Path,including riding the Thamesmead Ridgeway. Coffee stop at Lesnes Abbey Park, Abbey Wood. Just ruins, but extensive and well looked after. Part of our regular Southwark Cyclists Healthy Rides series. More info at www.healthyrider.weebly.com
