For anyone interested in this event, I have one spare space even though the entry system is closed to avoid an overshoot of the 30 limit. Just drop me a line and I will give you my paypal details.
There are few calendar events that trespass into the Begwyns and certainly none that visit the ancient monument of Arthur's Stones. Though there are plenty that go to Hay-on-Wye on account of its numerous cafes. Whatever the case, there are certainly none heading out of Worcestershire and the West Midlands to these destinations until now.
Looks a cracking route but I think your certainty is incorrect, my Monmouthshire Monster 150k has an info control at Arthur's Stones and it goes up the hard side of Pentre Lane to get there too. It's immediately followed by a climb of Snodhill Old Tay to add to the monstrousness . It may or not run this season owing to obvious issues in Wales, which may a shame as Herefordshire have kindly recently resurfaced Snodhill.
Since the sad demise of the Gladestry and Merthyr audaxes I'm not aware of any events in the south Radnor Hills though.
Ooo, I better correct my description for fear of mis-selling but thanks for the information. Coming down Pentre Lane I did think, thank god I am not ascending this horror.
With the Begwyns, I know that some perms pass through them, such as the Cambrian Perms and a couple of John Hamilton's routes.
