Hi Mike
Check out the Southwark Cyclists website for all the details.

It starts in East London and you ride through the night to arrive in Dunwich on Sunday morning, approx 120 miles.
It's a tough ride, but well worth doing, and at least you've got a short ride home afterwards
You've got a few months to get some more miles under your belt, and if you can do it with some friends it will be a lot easier, or join in with the Cycle Chat peloton.
