Interesting, I've done all those roads on separate routes but never linked them up to go Hornsea. There is Saturday's ride planned, which I think I will complete with a ride down to Withernsea, and depending on how hungover energetic I am, either straight to Hedon and back to Hull or down to Patrington, Sunk Island, Cherry Cobb Sands Land (nice, but boring) ,Paull and Hedon road to Hull.
Currently I take a pretty simple route of Hull to Beverley, to Leven, to Hornsea, Aldbrough, Sproatley, Bilton and back to Hull which is 43 miles. It's OK but between Leven and Hornsea it's busier the more sun there is, for obvious reasons!
Back in the days 26 miles was a long ride, I used to do Hull to Beverley, Routh, Benningholme and Swine. And as I got further I used to do the Hornsea route but turn off before Hornsea and ride around the roads around Sigglesthorne, Rise and Burton Constable. These were my winter rides as I was beginning. I do these rides on an evening now after work; only 4 months ago these were reserved for a weekend, with a good breakfast before hand, but it's amazing how the landscape has changed, lots of green on trees and green in the fields.
