If you see a runner experiencing difficulties during Ultra Wales please inform Checkpoint Marshals. Each runner should store the mobile number of Race HQ in their telephone. The contact number will be provided in your race instructions.

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. Between checkpoints 1 and 2, the course runs along a quiet country road. Please ensure you stay to the side of the road and be aware of vehicles.

There are certain sections that lead onto country road, and/or road crossings and care should be exercised in these locations.It is the role of the entrant to be self-sufficient throughout the event.

Our team will endeavour to reach any participant in difficulty as soon as possible however please note that due to the inaccessibility of the Trail in certain locations, this can take time.. 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.

SUPPORTERS / CREWS – GB Ultras request compliance that Supporters (friends and family) and Support Crews do not ATTEND CERTAIN CHECKPOINTS due to safety concerns based on large numbers of vehicles attending locations. These maybe due to busy road crossing, limited parking, increased likelihood of blocking access/egress in case of an emergency. Please note, race rules, time penalties/disqualification may apply to their runner.

**DUE TO LIMITED PARKING AT CHECKPOINT LOCATIONS AND THE START/FINISH VENUE, A SINGLE VEHICLE PER RUNNER IS PERMITTED. SUPPORT TEAMS MUST NOT ARRIVE AT CHECKPOINTS ANY EARLIER THAN 30 MINUTES BEFORE THE EXPECTED TIME OF THEIR RUNNER**

Please note, due to parking limitations, Supporters (including Crews / Friends & Family) are not permitted to travel to the following locations:

Checkpoint 5
Checkpoint 6

Parking locations at all checkpoints are pay and display.

Supporters risk the disqualification of their runner or time penalities being applied if they are present at any of the above locations where we have stated they are not permitted to travel to. Your race instructions will include a specific section on Supporters and will provide further details.

At other checkpoint locations, no more than two Supporters per participant are permitted at a checkpoint at any one time.  These must not impede the Event team nor other runners.  

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

Supporters must take their rubbish with them – they are not permitted to leave rubbish at checkpoints.

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

No dogs are permitted at checkpoints.
