Nope – Malverns down to Welland is significantly steeper – though I’ve only ever ridden up that, not down, so no idea whether or not it’s a 50 hill. Don’t even break 40 going down towards Ledbury though IIRC.
Yeah, the roads off the top of the Malverns especially down to Ledbury, in any direction, are all quite long, but nothing like as steep as the start of the road to Welland.
And as for it being a 50 hill, if I can do 48 on it with little effort, someone covered head to toe in skin tight lycra, with a decent aero tuck and a good set of legs to get good acceleration off the sharp left hand bend, should probably be able to push 55+ coming down there, maybe even 60 before the road starts levelling out. But you’d need to REALLY gun it out the corner for sure.
Oh, and I’m sure some eye protection would help too, I backed off a bit mainly cos I couldn’t see anything cos my eyes were streaming!
