Does anyone know of or can think of any suitable memorable climbing challenges for the summer?
context, I'm in year 11 so have my 2 month July, August holiday, would like to climb hard but use the time to do something I'm really proud of. I climb mid F7's and HVS, but grades aren't important really.
I would like to do something like a mini sufferfest adventure, but more enjoyable. Any ideas would be much appreciated?

I did the Gritstone Gallop last year and plan to do it again this year - 12 routes over 12 crags, theoretically covering 12 miles in 12 hours. In actual fact it took us more like 15 hours to complete and we might well have done rather more than 12 miles so it's better to do it in June when the days are longest. However, if you're organised you could do it in July. You start off at Stanage North and finish at Birchens in the version we did.
