It is the role of the entrant to be self-sufficient. Should an incident occur, our team will endeavour to reach any participant in difficulty as quickly as possible, with Event staff stationed in hard to reach locations. Phones must be used only in an emergency to conserve battery power should the need arise.

Participants who lose time helping another fallen participant, can claim this time back, subject to RD discretion and under the proviso of completing within RD agreed conditions. Please note any extended time will be ‘within’ the cut-offs of the event, due to event staffing, medical cover and venue hire.

GB Race Tracker provide the Live Online GPS Tracking for the event with updates on participant positions approximately every 2 minutes (subject to signal). On the front of each tracker is an SOS button which when pressed immediately alerts the Race Director & Race HQ that urgent help is required who can then act accordingly.

In the event of a Medical Emergency please call Race HQ first.

Runners can utilise a Dropbag facility to transport a change of kit to the Finish line venue.

This dropbag should be handed in at Race Registration in Talybont-on-Usk, be labelled (labels available at Race HQ) and should be small/medium in size (i.e. not a suitcase). They will be transported to the finish line venue for runners to collect at Llangadog.

Support crews are more than welcome to pick up dropbag’s providing prior authorisation is given by the runner (at Race Registration) and early collection by the runner is fine too.

Optional coach travel back to Talybont-on-Usk is available at a cost of £19.99 per person.
Coach departs Llangadog Community Centre to Talybont at TBC (Approx 9am Sunday).

Runners can rest at the finish venue while awaiting coach transport.

Training Runs

All ‘entrants’ are invited to join the Team on training runs covering key sections of the Beacons Way Ultra 105km route prior to Race day. You can attend as many as you like, one day or both days of any given training weekend with the aim of learning the route and increasing confidence come Race day. You’ll also have the chance to meet other runners taking on the Race.  Training runs will have a small charge of £19.99 for 1 day or £34.99 for both days for attendance. Included is –

  • Fully guided recce run
  • Mandatory Kit Advice
  • Exclusive group messenger chat for recce and race prep
  • Limited edition buff
  • Meet the team
  • Gain trail experience and knowledge

Pace wise we’ll be going at a nice gentle pace ensuring all runners stay as a group with brief stops approximately every mile. Generally our training runs have high attendance and for safety reasons we’ll be imposing a limit depending on feedback and Covid-19 restrictions.

Weather conditions can change very quickly in the mountains so we recommend runners refer to the Mandatory kit section and carry sufficient food/water for the duration of each of the runs.  No overnight accommodation is included. However, runners may be interested to learn that there are a number of campsites’ spanning the trail and these would be a good choice for training run overnight stops.
