As a UK Zwifter I love the London circuit especially as I work in central London. Could you have special features enabled such as when you complete a certain number of circuits past certain buildings you receive a notification or on special dates. For example this year the Royal Air Force celebrated their 100th year since inception and there were a number of events during the summer. You could have flown the Red Arrows down the Mall or hang a special flag outside the RAF Club in Mayfair which we cycle past, or when the guards change at Buckingham Palace. London has a very rich history and I am sure some of that could be brought to life in a subtle manner while Zwifting.
