That bits clear to me, after the short drag stay close to the fence until it drops down a bit then you pick up the very clear path that traverses South following the a470. It's probably a little bit longer but very easy going.
Maybe, I've only done WRD once though in 2012 coming in ~5.30'ish, I did the Rhondda Rollercoaster the same year in ~5.00. Never done the Caerphilly Summits as I'm fairly new to this caper. I've managed a bunch of MCN events though but had to skip last year due to illness.
I'd to do WRD this year too but it clashes with the Gower 50, and I reckon I deserve something flat
I know what you mean about the LL, but the route from Coniston is completely worth the dark places you visit from Ambleside onwards.
Good luck Circlip, I hope you get a taste of typical Beacons weather; glorious sunshine, pea soup,and hail all within a couple of hours.
Where Ravens Dare is my local long run T Rex; it's a superb route amongst the most unlikely backdrop.
Training is sketchy, I've no more spare days between now and then as I've got the kids for the last two weeks of the holidays and we're holidaying every weekend - it's a bit antisocial stealing long runs when we're away. I think I'll have some training effect from the LL100 to see me through though.
