For the record:
I clocked it at 3.76 miles LITTLE Sca Fell summit to gate at Longlands onto road. You have to pedal up from Great Sca Fell onto Little Sca Fell to begin descent so that bit doesn't count.
Height Loss:418m
Time descending: 8 mins (includes photo stop at signpost near bottom) & I am sure aomeone will be along shortly to say they have done it in a quarter of the time blindfolded on a fully rigid unicycle
Grin factor: 100%
Effort to get there: 99.9%
Gav, I have to add I made about half a dozen pedal strokes in total near the bottomto keep speed up but could prob just have got down without
Summit of Little Sca Fell looking down to Longlands
Postscript: I would say that at least 5km of Bowderdale is pedalling Not descending
