I should have known better really!
The hill I wanted to play with - The Burway at Church Stretton - is a fantastic little gradient. 20% at its steepest, so perfect for multiple reps.
But it gets abandoned in the winter - there's even a sign at the bottom telling you that!
So I drove up it as I'd planned to the car park at the top. And it was pretty lairy on 4 wheels.
2 wheels would have been just silly.
I'll be back though - it's perfect for what I want :o)
