The sort of RIDER who runs out of road on Greenhow Hill will also run out of road on Peat Lane.
Greenhow Hill is a wide road with reasonable sight lines most of the time.
I have tried to link the start of the tricky bit of the descent of Peat Lane.....its the worst bit of film I have seen from the Google van....
https://www.google.co.uk/maps/@54.074111,-1.769164,3a,75y,90h,49.44t/data=!3m6!1e1!3m4!1sIghmynM4PqmAnYEeH9kv2A!2e0!7i13312!8i6656You can come flying down a straightforward descent (narrow, but open with reasonable sight lines) to be faced with this....the road dives into a tunnel of trees, the stone walls converge to line the gutters. The road is liable to be covered in debris washed down, there is no fast motor traffic to clear the debris. Right on the bend there is a stone water-bar in the road surface.......how close did you have to get to see it on the Google image? How soon would you see it plunging into the semi-darkness under the trees, wearing fashionable cycling sunglasses?
Follow down Peat Lane on Google until you get to the house on the left, and thats the worst of it finished......if you make the first bend, you will be going slow enough to make the rest.
There is an excellent farm cafe at the top of Greenhow Hill, I went there with a group of "new cyclists". We went up Peat Lane, (walking the steep bit), the plan was to return via Duck Street, but that was closed by a road traffic accident (one of the quarry lorries in the ditch). Nobody fancied going down Greenhow Hill, so we went back down Peat Lane. We got to just above my link (where the camper van is parked ) and everybody else got off and walked: I was the only one to ride down the tricky bit.
They all think I am reckless, I'm inclined to think they lack skill.........but perhaps I would have got off and walked if I had been on a fashionable bike with twitchy steering, narrow tyres and dual pivot brakes.
My view is that anybody whose brakes work can get down Greenhow Hill in safety if they exercise reasonable care, but I would not send an inexperienced rider down Peat Lane on their own.
