The last time I tried the old Withernsea line, 2016, it was absolutely terrible on a hybrid with 32mm tyres. If you have wider tyres and suspension it may be much more comfortable.
(In fact, after 10 miles, my shifter broke apart with all the vibration so I took the next exit, and rode back on the road with just my front shifter working).
