Black Cattle Ultra Gwartheg Duon

The Black Cattle Ultra is a point to point trail event following the Cambrian Way through South Wales, finishing at Cardiff Harlequins RFC in Whitchurch, Cardiff CF14 7JN. The route passes upland peaks, woodland paths, heather moor and Castell Coch near the finish, and includes named landmarks such as Llanthony Abbey, Pen-y-Fal (Sugarloaf), Twmbarlwm and Mynydd Machen.

Two distance options are offered:

  • 44 miles route from Llanthony Priory to Cardiff
  • 33 miles route starting in Abergavenny and joining the main route

Both courses require self-navigation; the route is not marked and competitors follow Cambrian Way markers into Tongwynlais and then the Taff Trail for the final miles. GPX files of the route are available. The event provides live tracking devices, a professional medical team, professional timing and a photographer. The 44 mile race has three indoor aid stations and the 33 mile race has two indoor aid stations, with additional water points about every six miles. Indoor aid stations include Abergavenny Community Centre, Pontypool Pontymoil Church and Machen. Flushable toilets will be provided at the indoor aid stations.

Entrants must be 18 or older. Entry fees are listed as £95 for 44 miles and £85 for 33 miles. The event is organised by Ridge Runners, a not for profit trail events company run with volunteer support and an emphasis on environmental responsibility and inclusivity. A kit check is carried out at registration; a full kit list is provided by the organiser. Parking, changing rooms and showers are available at the finish venue. Optional extras include start line transport and a finisher memento sourced locally. Visit the organization's website for the most recent information.
