Both climbers familiar with the location but not the route. Warm day and first time climbing on limestone and first multi pitch this year. We had been out several times on grit. Did pitch one fairly confidently but didn’t feel my head game was all there on the lead. Started pitch 2 and was able to put in 2 pieces of decent pro. Started to move up through the layback flake and was a little hubristic about needing more gear placements so was a little run out. Fell off route about 3.5m above last gear after my foot slipped. Both bits of gear held (purple dam cam and number 9 rock) Ended up upside down on my back. General scapes and cuts to arm and back. Also a sore ankle. Glad for the helmet and my belayer. They did brilliantly from their hanging belay. Especially considering I was out of sight. I was able to get back on route and settle myself. I then spent a little time placing a couple of bits of pro for the section I fell off and finished the route. Brought up my second and we abbed off.
