Last of the Summer Winos
- Location
- Holmfirth.
The toughest ride I've done in the Uk is "Le Terrier", a sportive in the Forest of Bowland.

3,800m climbing in 100 miles!
Compares well with Holmfirth CCs annual sportive which hits about 3400m in 88 miles.
Its running again this summer for anyone interested: https://www.britishcycling.org.uk/events/details/156469/Le-Cote-de-Holme-Moss-Sportive
It finishes off with the Strines,(admittedly in the easier direction, but suspect it will be enough given the rest of the route).
