Open House - a chance to visit some of London's outstanding architecture, including places not normally open to the public. Numbers will be limited on this to ensure we don't spend too much time queuing - but we will run up to three separate groups depending on demand. Please contact Caroline in advance to book a place - ideally a few days before, but feel free to call on the morning before 08.45 as there may be spaces still available. An easy ride but some busy roads, probably only about 15-18 miles in total. Meeting time will be around 9.15-9.30am - details will be advised to those who have booked on the ride.
