L2B + or our version of it. David plotted a route to include Ditchling Beacon, ignore the uninteresting London section and add just a bit more challenge in the form of 80 miles long route and 4600ft climb. Of course GPSEd crashed again so the route is incomplete the route here is edited to complete the actual course.
The route was in fact 80.28 miles long and we averaged 16.2 miles/hour. Great ride and more importantly no pushing or stopping on Ditchling beacon or any other hill despite that seeming like a very appealing option around Groombridge.
