When is it? I can't see it in any calendar
traditionally it's August bank holiday weekend or there abouts but it may of changed since I last did it. Good to practice in the heat it's a hard race on a hot day. You need to know what your water strategy is. After one terrible anti clockwise final ridge where I was very glad to blag a drink from a family having a picnic just before tor-y-fol I always used to dump a couple of bottles in prep if it was hot. Going the other way you need to know where the springs are just off the ridge.
My guess would be 12th August (is Aug still missing from WFRA site?) based on last year beibg week after S6D. If only the organiser read attackpoint rather than rest up after trifling little bike ride yesterday ;-)
We were carrying a litre or so each and had 2L stashed away just after Torpantau pass but still run out and struggling from Fan y Big.
Lovely little bit of shade behind the building on the dam - could have done with a bit more breeze though!
The date changes every year as I have to fit it in with my Adventure Racing.
