Actually you can. or at least break it into a few smaller bits Pocklington to Londesborough, a short sharp bit after Burnby, Londesborough almost to Mkt Weighton, a big dip then a reasonalble up bit, made easier cos you can get a good run at it , turning off for Goodmanham just before you get there. Take the first right and theres a short sharp hill and youre then on the lower Wolds above Market Weighton.
Or you can take the road through Nunburnholme up to Warter, a bit of a climb, but the climb from Warter to North Dalton isnt that bad
