In reply to andy:
Saw both races near Wentworth on Friday, with a long ride along some of the course in between. Every year I expect the novelty to have worn off and people to have lost interest, but no - every village it passes through seems to make a bit effort, and loads of people by the roadside for both races.
And it really does show how much lovely countryside there is in the county - even that bit between Barnsley and Rotherham !
Park Rash on Sunday looked incredible :

So the Worlds next year and maybe the Vuelta in 2020. The vuelta does like it's crazy steep climbs and there's plenty of those around.
