Hi, I ride in each day on the A164 from Beverley to Hessle. So that's up to Skidby Mill and then down and up to Castle Hill before slipping off behind the Ramada Jarvis through Willerby.
BTW I don't use the cycle path they have along that stretch as it swaps from one side of the road to the other and it's a PITA trying to cross the road when it's busy.
So is that hilly 'cos it sure feels like it sometimes! Mind you I'm on a twelve year old MTB with some Nokia road tyres, and panniers carrying a change of clothes for work, spare tubes (2 visits from the p*nct*r* fairy in last 3 weeks so far this year!), and loads of other stuff I probably don't need, so it's not very "lightweight".
When the weather improves I'll be back on the full route which is Bridlington to Hessle along the A165 - A1035 - A164; the A165 is rather more undulating than hilly, but after a day at work and a couple of hours of cycling the last bit seems like hard work.
