The climb of Mow Cop, which features in Simon Warren's 100 Greatest Cycling Climbs book. Filmed during the 2017 Cheshire Cat sportive, it's not usually that busy!
Went up there today on the Cheshire Cat sportive... had to walk on that 25% section... the rest itself was fine. However you and your friend are something else- you made it look sooo easy!
Very good effort! I did it today too, although not as quickly as you (I managed 8:46, about 10 seconds slower than my last attempt). Is your BPM accurate there? Mine was closer to 190 at the 25% section.
