16m. Starting underneath the mid height roof,climb the tricky to start crack to the roof then using a small crescent shaped crack to the right surmount the roof and finish up the wall above. Well protected where its needed.
In the NE England guide (2003) the line on the diagram (pg 88) should be slightly further right (the crescent-shaped crack is just right of the long roof).
