We were near the end P2 of the The Angel's Girdle route at Wintour's Leap when the incident occurred. The route is given VS and both of us are very comfortable on multipitches at this grade and above and have been trad climbing for 6+ years.

The route is a long traverse of the North Wall at the crag. Near the end of the pitch the leader had climbed up onto the E1 traverse that goes above the VS and then back down to the belay, as the guidebook description regarding a sapling was found to be confusing. I was following this higher section when a large (big microwave-sized) block I was holding onto broke off. The next gear protecting me on the traverse was reasonably far away and I fell sideways around 6 metres. The rock I fell past is quite slabby and protruding and it was not a clean fall - my foot must have clipped a ledge and began to swell significantly and I could not put weight on it. I felt like I was going to pass out and hobbled along the rest of the pitch and was backroped to the belay, leaving a piece of gear in, and we abseiled from the tree at the end of P2 and commenced the journey out from the crag (mostly via me being carried).
