Have to agree with the earlier comments: this is such a lazy course design and such a hugely wasted opportunity. Even with the constraint of the Harrogate finish it did not take much imagination to come up with a vastly more interesting and testing route. They should have approached Harrogate...
Re:
Just over 50km: 10km or so of up and down after Greenhow Hill until Grassington. Then 15km of nice narrow windy roads before a long stretch on main road up to settle and finishing circuit
Just driven up to Greenhow. It's snowing up there but not settling on road. About 100 hardy souls in position already. Passing quite a few fans riding out as I head back down. Home for lunch and back with bike in couple of hours.
Gary Verity just tweeted picture of current situation on Greenhow Hill and there is several hours of snow forecast tonight for this area although at this time of year it should clear quickly tomorrow from roads at least
