First time climbing at Roaches. After climbing several routes throughout the day (mostly S/HS) I decided to lead Raven Rock Gully for an easy lead for the final climb of the day. I followed the Topo on the Rockfax app, moving left approximately half way up the climb to the central block. The move was an awkward overhang onto a sloper which felt too hard for the grade. I was protected by what I thought was a good thread approx 2m below the hard move. Slipped & fell on the climb up and the thread broke, leading to an 8m or so fall. Only other gear was below half height so decked out. Lead to broken collarbone and some other minor leg and back bumps.
