You wouldn’t be on your own straggling on long mynd!
Historically, I’ve started the ride either climbing out of carding mill valley or The Batch.
Both are long and steep in places. I have managed to ride up all of The Batch until the really steep scramble at the end. Only to be confronted by the less steep, but grassy and 95% cert to be into a headwind climb onto the ridge proper. Burned.
In a way I prefer the climbs in the Peaks as they have more technical interest, tend to be a bit more sheltered, and they don’t egg you on by seeming do-able when they get really serious!
Many peaks climbs just prompt my inner voice to say “no chance, sunshine, save your legs and walk”!
But some people have cleaned Jacob’s as a climb! Literally unbelievable. I’ve stood at the bottom numerous times and been absolutely mystified as to how you could ride up that, even if you were inhumanly fit.
