The ultimate night ride is back for its 14th year on Saturday 8 July 2006, from 9pm to dawn on the Sunday morning.
The 120 mile route is from London Fields to Dunwich Beach, Suffolk. I have put the route online via the very cool Gmap-Pedometer site here (based on Patrick Field’s notes).
For more info on the Dunwich Dynamo see the FAQ by Barry Mason of Southwark Cyclists and a nice account of the 2005 Dynamo at rapha.cc.
The Bike Show featured the 2004 Dynamo, MP3 download or listen in Real Audio.
