Are you just looking to tick off some classics or stringing a route together? Winnat’s Pass is an obvious contender, with some great surrounding roads to build into a route. However if you want something quieter and less obvious, you could do worse than head into the Staffordshire Moorlands. Plenty of little gems there.

Few little back roads round here to choose from as well:
Chapel-en-le-Frith

There’s loads with short sections.

Coombs to Castle Naze will give you some 30%+ bits.

That looks good and starts 200yds from my house…..no route though? If you’re keen Rob J I’ll happily join you? I’m very average but have done a few Sportives ….. Cakes and coffee my speciality ;0)

Bank Road, Matlock

It’s West Yorkshire you need to come to mate, 20% round here is average. 🙁

Shibden Wall to start you on, then head off down to Keighley then the Calder valley to finish you off.

I drive down a lot of out of the way roads round these parts for my job and I went down a road which was cobbled but at the bottom was so steep I had to have 3 goes getting round it as I thought I was going to ground the car.

Gorsey brow, broadbottom.
Riber road Matlock.

I’d check with Mike at Peli Deli as to which route they’re doing, and how hard it’ll be. The start venue and ride description are different on the official leaflet, too:
