Very techy route, you’ll carry a lot of the way from Stockley Bridge to styhead except the last bit, most of the way to Angle tarn is rideable if your fit and are a good technical climber. Riding it the other way is superb a real rocky test(seem to remember a certain singletrack journo needing the keswick mountain rescue after a spill on the rocks). Super steep and rocky to the bridge but doable. I’d be tempted to do it the other way. Still a very tough route, not one to attempt in poor weather.
Greenup Edge has some great stuff on it but some of it is unrideable, nowt worst than carrying down!!
