If you see a runner experiencing difficulties during Ultra Wales please inform Checkpoint Marshals. Each runner has Head Quarters mobile numbers on their bib.

No roads are closed en route so please exercise due diligence and care at all times. This will mean that participants have to slow, possibly stop to cross roads.

There are certain sections that lead onto country road, and/or road crossings – due to the length of the route – it won’t be possible to marshal a 50 mile route. It is the role of the entrant to be self-sufficient.

Our team will endeavour to reach any participant in difficulty within 30 minutes to 1 hour due to the inaccessibility of the Trail. Medical staff will be dispatched as quickly as possible. Phones must be used only in emergency to conserve battery power should the need arise.

Participants who lose time helping another fallen participant, struggling against the cut off time due to this reason, can claim this time back, subject to RD discretion, Checkpoint/Village Hall availability, and under the proviso of completing within their new, extended cut off period.

GB Ultras believe all participants should make proper and mindful transport arrangements prior to the event and NO participant should be in charge of a car directly after the event. Please make sensible arrangements.

Please note Support Crew restrictions at:

Checkpoint 5  – No support crews permitted

Checkpoint 6  – No support crews permitted

At other checkpoint locations, no more than two Support Crew members supporting an individual runner are permitted at a checkpoint at any one time.  These must not impede the Event team nor other runners.  

Parking locations at all checkpoints are pay and display.

Support crews must not take the food nor drink from the checkpoint except for their runner unless given permission to do so.

Support Crews must respect instructions given by Event Staff.  Failure to do so will result in the Support crew being asked to leave the checkpoint and possible time implications or disqualification of the runner.

No dogs are permitted at checkpoints.

During the race

Please inform a GB Ultras Race Marshal at one of the Checkpoint’s or Race HQ.  This will ensure all participants who are registered and pull out of the race are accounted for, allowing for the accurate and safe running of the event.  If a participant withdraws at a Checkpoint they must hand over their Race Number & GPS Tracker to the Event team to signal their retirement.  Marshals will inform the race organiser and each of the remaining Checkpoints can update their event documentation.

Upon withdrawal from the race, it is the responsibility of the individual to get themselves home (or to the finish if required to collect their dropbag). We would recommend having your own Support Crew or someone on standby to collect you in case of unexpected withdrawal during the event.

Where possible, runners withdrawing from the race may be able to be transported by GB Ultras event support from a checkpoint back to Race HQ however this cannot be guaranteed. Priority will be given to runners still participating in the race.

Where it is possible to transport a runner to the finish, this will only be available after a checkpoint closes and therefore may involve a significant wait. In addition, as event teams are deployed to multiple checkpoint locations, transport to Race HQ may involve intermediate stops on route for further (potentially lengthy) periods of time before heading to Race HQ.

GB Ultras also reserve the right to pull any participant out of the race on health grounds.
