The BlackCattle Ultra August 14th 2027

 A 44 or 33 mile adventure traversing the Cambrian Way!

Join us on a stunning 44 or 33 mile journey along the Cambrian Way through South Wales, starting in either Llanthony or Abergavenny, climbing some of the most memorable peaks of the area along the way to Cardiff. You’ll be rewarded with some gnarly climbs, breathtaking views, quiet woodland paths, purple heather covered moors and even a fairytale castle near the end; a hugely satisfying adventure. You’ll be back for more…

 The Cambrian Way

 Established in 1968, the Cambrian Way is a high level walking route through some of the most wild and beautiful areas of Wales, following rights of way and running from Cardiff all the way to Conwy in the north. Our ultra route follows the path from Llanthony Abbey in Monmouthshire all the way to Cardiff, ending at Cardiff Harlequins HQ in Radyr.

 If you love running in peaceful solitude and you love your scenery to be wild and rugged, but you also like to feel fully supported with live tracking and three indoor aid stations (plus additional water stops every 6 miles) this is the event for you!

 Points of interest along the way:

 Llanthony Abbey

Garn Wen

Twyn y Gaer

Pen-y-Fal (Sugarloaf)

Blorens

Mynydd y Garn Fawr

Twr Ffoledd (Folly Tower)

Twmbarlwm

Mynydd Machen

Cefn On

Fforest Fawr

Castell Coch

44 mile - 71K Ultra

The race starts at the beautiful Llanthony Priory.

 33 mile - 53K Ultra

This is not the easy” option. The race starts 11 miles into the 44 mile route, in the pretty town of Abergavenny.

 Why the name?

 The race starts in the heart of the Black Mountains - and the local cattle are called Welsh Blacks. We are celebrating both the outstanding beauty of the area - and the local hardy breeds that cope with the Welsh mountain weather. The calves are so cwtchable, you'll want to take one home!
