Beckenham to Greenwich Park?

We will follow the Waterlink Way (NCR 21) beside the Pool and Ravensbourne rivers to Lewisham then up to, and across, Blackheath to the top of Greenwich Park. Here we will stop for an ice cream and take in the views across the Thames from The Shard to Canary Wharf before turning back. http://www.gmap-pedometer.com/?r=6381727 The route is flat (apart from a short climb up to Blackheath) and is mostly off road on good surfaces, so will be suitable for all bikes. It will be around 12 miles in total and shouldn't take more than 1hr 40min of cycling. Meet at Kent House station (outside ticket office) at 12pm (a second joining point can be arranged in Catford if requested). The ride will end back at the Crystal Palace Park cafe for refreshments. The small print: I am not a qualified cycle leader so you attend at your own risk. For further information visithttp://www.meetup.com/The-Sydenham-Crystal-Palace-Forest-Hill-social/events/203526422/
