Weather

The path involves low-level running, with the highest point being Holyhead Mountain / Mynydd Twr at 720ft (220m). While it is possible to complete the route in harsh weather, the path is often exposed to the elements. Prepare for high winds and rain.

Runners are responsible for monitoring the forecast and preparing accordingly. You must arrive equipped for high winds, heavy rain, and cold temperatures – especially during night stages or when fatigued. Check the forecast before arrival and throughout the weekend using trusted sources such as the Met Office. Your safety depends on your preparation.

Clothing and Gear

Layering:  Wear a waterproof jacket with taped seams (mandatory), ideally with high visibility for safety. A pair of leggings or running tights under shorts will help retain warmth.

Accessories: Gloves and a hat/buff are strongly advised for wintry weather.

Preparedness: Ensure you have enough clothing and waterproofs to stay warm and dry, regardless of the forecast. Exposure can set in quickly when stationary, so get out of the wind and add an additional layer while resting.

Night-time Navigation

Expect to run in darkness. Uneven terrain and hidden hazards increase the risk of trips and falls.

• Use a head torch (minimum 200 lumens, mandatory) and carry spare batteries or a backup torch.
• Wear Hi-Visibility clothing and a rear-facing red light (mandatory) on roads.
• Consider a GPS device if unsure of your navigation skills.
• Teaming up with others at night is encouraged.

Fatigue, Cold, and Hypothermia

The race will test you both mentally and physically. Many runners will be operating at their absolute limits, which can affect decision-making. It’s vital to take on sufficient fuel before and during the race. Recognise when you need more food and water; noticing energy drops and addressing them is key to both performance and preventing hypothermia.

Understand the gradual effects of cold and plan for wind chill. Warm, dry clothing is essential to stave off cold and prevent hypothermia. Pay particular attention to keeping your extremities – head, neck, and hands – warm.

It takes experience and courage to decide not to push on, especially in a group. Be extra cautious in any combination of wet, wind, and cold conditions. As a general rule, if you’re questioning whether to continue, the answer is probably ‘no.’ Always keep something in reserve for contingencies, dress appropriately, and watch for symptoms of exposure and fatigue in others.

Cliff Tops

The route follows the cliff tops closely in several locations, and runners are reminded to stay on the path for their safety. Take extra care when running on cliff tops, as the path can be narrow and exposed. Caution is needed on wet grass and mud, which can be very slippery. Trail running shoes are recommended for their extra grip in wet and muddy conditions.

Livestock

When traveling through a field with cattle, pass steadily around the herd, giving them a wide berth. Running may cause them to run too – it’s best to walk until you’re clear of the cattle. If you encounter a cow with a calf, take extra care not to come between them and give them plenty of room.

Tides

Sections of the path may be restricted by the rise and fall of the tide. During periods of spring tides, particular care is required. Do not attempt to ford rivers, estuaries, or any open water. There is always an inland option of comparable distance, which will be discussed during the event briefing, and highlighted at checkpoints throughout the route.

Mobile Reception

Mobile reception can be patchy or non-existent in some areas. Be aware that it may not always be possible to call for help.

Medical and Assisting Injured Runners

In the event of a medical emergency, call 999. If you’re injured but can walk, make your way to the nearest checkpoint for assistance. For help getting back to a checkpoint or other issues, contact the Race Directors. Be aware that some sections are remote and response times may vary. Always stop to help fellow runners in need.
