Participants can utilise a Dropbag facility to take two dropbags. One dropbag from the start to meet them at Checkpoint 5 with an additional dropbag to meet them at the finish line.

As an example, a dropbag may contain a change of clothes, etc to meet you at the finish venue.  Any dropbag should be clearly labelled with the participant’s Surname & Race number at Registration. Labels will be provided at Race Registration on race morning.

Dropbags can be left before 11:40 during race registration with the Event Team in a designated area.

We cannot accept liability for lost or stolen bags.

Support crews are more than welcome to pick up dropbags providing prior authorisation is given by the runner (at Race Registration) and early collection by the runner is fine too.  Please note dropbags from Checkpoint 5 will only make their way to the finish venue when the checkpoint in question closes.

In the event that you withdraw from the race before reaching the finish, you must collect your dropbags from the finish venue.  Dropbags will not be transported to locations along the route.  Any dropbags not collected from the finish line will be disposed of after the event.  We are not able to post out dropbags that are not collected.

The results will be available real-time during the event and we’ll update this page with the link prior to the event.

As each runner crosses the finish line, their race chip records their individual finishing position and finishing time.

Your position and time shown in the results link is your official result. Please note that the tracking system is different to the timing system and has no bearing on your chip time or result.

If you see a runner experiencing difficulties please inform Checkpoint Marshals. Each runner should have RACE HQ mobile numbers stored in their phone (shared in the Race Instructions email in the weeks prior to the event).

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.

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

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 and also not at the finish at Llangadog RFC.
