In reply to aphex:
It's a fair question though. Granted I know bugger all about climbing 8B+/8C, but if a climb 8B+ in the UKC logbooks, and in the linked news article it says:
"Needless to say none of the repeaters has used the same beta and the problem has, consequently, been downgraded to ~8B+."
it does seem odd to be claiming a 8C ascent without some sort of justification/explanation.
Asking this question takes nothing away from a hugely impressive ascent, which is possibly the first 8C problem done by a Brit in the forest (?), but does seem sloppy reporting.
