Athletes can board the complementary coaches that we have organised for you to get to the race start. The coaches are not mandatory; if you wish to get to the start under your own steam then please let us know.

There is ample parking at the race start.

NOTE: You will need to board the coaches changed and ready to race. Lots of parking at the Race Start so friends and family are welcome to see you at the Race Start.

Please be seated on the coach five minutes before the departure time to avoid missing the transfer. There are no alternative arrangements in place to take you to the race start if you miss the coach.

The race finishes on the grounds of Oystermouth Castle. Race finishers will receive a medal and be able to collect their drop bags and change. You will be asked to hand back your bib.

Safety Measures

Safety Measures

It is important that all athletes appreciate that safety first begins with yourself, your team, and each other. Take care of each other – it is a long, tough course.

All athletes must help one another in an emergency, whether this is on the Full course, Gritty course or Sprint course, team or solo. Communicate with event staff when help is needed as early communication is important.

We have a robust safety plan in place, with expert water safety and medical teams on the course. We also have cut offs in place at swim entries and at checkpoints for further safety measures. The compulsory race briefing will go through all safety measures in more detail.

We use cut off times to make sure that everyone completes the race safely and before dark. Cut offs are also critical for our safety plan for the positions and movements of boats and the medical team. Consequently, cut off times will be strictly enforced. If you miss a cut off, even by one minute, and continue to race, you will be disqualified from this and all future events we operate.

Cut off times are enforced at swim entries and at the checkpoint. Checkpoint cut off time is listed above in both the Route Card and Nutrition sections.

Our water safety plans are delivered by a professional organisation who specialise in the water safety of mass participation events across the UK and worldwide. Communicate with the teams if you need help or support at anytime in the water. Our safety briefing will go through what to do when in difficulty.

The water safety team will move to different sections of the course when swims open and close for athletes. If you don’t make a swim entry on time and miss the cut off, then you will not be allowed to enter the water as the water safety team will be moving on to a different part of the course.

Our medical and rescue plans are delivered by a professional organisation, based in the Lake District, who provide bespoke safety solutions for outdoor sports events.

Our medical teams will be positioned strategically around the course and move according to the timings of the athletes. A medical team will be stationed at the finish point throughout the time athletes cross the line.
