In reply to sparksy: It's in Sheffield, it's not bad, 2 bed, open plan kitchen/living, fully furnished.
The rules are, you have to attempt to the lead route, competently using a 'standard' rack for gritstone (with a few cams), everything in working order, place gear competently where it's available, stay on route. If you fall off, you have to hit the ground from high up, fully hard, in what a consensus of spectating climbers (who have not been briefed) agree is a 'groundfall'. You may get away without broken bones, as long as the climbers around agree it's lucky escape.
