The descent of Ullock Pike is a cracker.
If that’s the sort of riding you are after then the Borrowdale Bash is a bit boring and unrewarding, but good if you get caught on a rainy day. The Garburn Pass low level ride is also good for a rainy day. I would look at the descents off Helvellyn with my preference being Dollywagon and Grisedale the best, then Birk Side and then Sticks Pass if you’re after something less technical.
Other goodies include Wharnscale and various amounts of cheek. Nan Beild out and back is excellent if you like mega tech, if not the gentler southern descent can be worked into a number of loops, via Garburn Pass, High Street and Ill Bell being my favourite. So long as you avoid the very dull Gatescarth you won’t go.wrong round there.
