On August 24, 2017, I set out for a prep run up the Ha Ling NE Face at a moderate pace to prepare for an FKT attempt. After reaching the summit in just under two hours it seemed prudent to just run the descent as an FKT was likely. A sub two hour time for this route is definitely possible.
There were three spots on this route that felt quite sporting unroped: the rising traverse on pitch 5, the small roof on pitch 8(?) and a couple moves on the Great Dihedral slab pitch.
My car to car time for soloing the NE Face of Ha Ling: 2 hours 19 minutes (click for gps on Strava).
