One that isn’t in there is Long Hill
This hill here going from Whaley Bridge over to Buxton
which is used in the local club HC and will be the venue for the National HC next year.
Record on that used to be held by Rob Hayles but it was beaten recently and is now 12.26 (an average speed of 21.5mph!)
I’ve done Jubilee Tower many times on both training runs and in HC competitions. Tough hill, really difficult to pace yourself on.
Your right spacemonkey, not sure what the selection criteria was. It seems that it has partly been done to give a even spread around the country.
I think one of the criteria for hills included was that a lot of them are the venue for local club hill climb races (Titsey Hill was the one for my cycle club when I lived in London).
