I've done Holme Moss, Devil's Staircase and the Long Mynd; but the one that I know might defeat me is
Church Hill, Glyn Ceiriog.
It is a 2 mile long, 1 in 4 hill and I suspect that in parts, it is even steeper than that. I've yet to pluck up courage to do it . . . . . . I think that I'd need a mountain bike - and the more appropriate gearing.
I came down it once, with my youngster on a 'tag-a-long'; I was pretty much 'full-on' the brakes, all the way down.
Descriptions from a couple of websites:
from
Cheshire Roads CC . . .
"From Llanarmon D. C. there followed a brief breather as we followed the Afon Ceiriog downstream to Glyn Ceiriog to be met by the horrendous climb of Church Hill which rises like a wall from the top end of the village (two lots of double arrows on the O. S. map.
This bit of torture saw about 95% of the rider resorting to Shank’s Pony at some point or other (the exception amongst the Chesh being super fit Rob)"
from
Sherwood Cycling Club . . .
"A pleasant ride along the Ceiriog valley to Glyn Ceiriog and then the dreaded climb of Church Hill. This really was a brute of a climb, being about 2 miles long with the steepest section being 1 in 4 or steeper. I resorted to walking, as did most other people. Stephen managed to ride all the way up, passing scores of people and earning the nickname “little Indurain” in the process."
I'll try it one day, but I'll have to be very well prepared to tackle it.
It would be a great challenge for any Cyclechat rider . . . . who is going to be first ?
