We extend our sincere thanks to our sponsors for making this event possible:
Set against the awe-inspiring backdrop of Eryri (Snowdonia) National Park, the XTERRA Snowdonia Trail Marathon Eryri is a journey through some of the UK’s most striking natural landscapes. Starting and finishing in Llanberis, Wales’ outdoor capital, this event offers participants the chance to compete in one of the country’s most challenging and breathtaking trail races.
The meticulously crafted routes take runners on an unforgettable adventure through the park’s iconic trails and landmarks. Participants will experience panoramic views and tough climbs as they traverse legendary locations like Rhyd Ddu, Beddgelert, Nant Gwynant, Pen y Pass, and the mighty Yr Wyddfa (Snowdon), the highest peak in Wales.
For those taking on the challenge, this event promises not only a test of endurance but a celebration of the spirit of adventure, set amidst a landscape that will leave you inspired long after you’ve crossed the finish line.
Eryri is the Welsh name for Snowdonia, meaning "the land of eagles," reflecting the region’s rich wildlife heritage. While "Snowdonia" is the familiar English term, Eryri carries deep cultural significance in Wales and has been the official name of the national park since 2022, highlighting its proud Welsh identity.
Eryri is pronounced as "eh-RUH-ree" in Welsh, with the emphasis on the second syllable.
The Snowdonia Trail Marathon Eryri has earned its reputation as one of the UK’s most iconic trail running events, celebrated for its breathtaking scenery and demanding courses. Over the years, it has become a cornerstone of the UK trail running calendar, attracting participants eager to test their limits in the rugged landscapes of Eryri (Snowdonia) National Park.
In 2025, the event will reach a new pinnacle as it hosts the XTERRA Trail Run World Championship, marking the first time this prestigious competition will take place on European soil. This milestone cements Snowdonia’s status as a world-class trail running destination and brings together elite runners from across the globe to compete for the Half and Full Marathon World Championship titles.
This historic moment not only elevates the Snowdonia Trail Marathon to the global stage but also exemplifies the spirit of adventure and challenge that XTERRA embodies.
Travelling to Llanberis is straightforward, with multiple options available depending on your starting point. Whether arriving by train, car, or a combination of both, the journey offers plenty of opportunities to soak in the beautiful Welsh countryside along the way. Below are the best routes for international and domestic travellers:
Driving offers flexibility and the chance to explore North Wales at your own pace. The route to Llanberis includes scenic countryside views and the option to stop at various attractions along the way. If driving, ensure you’re familiar with UK driving regulations, such as driving on the left side of the road. Parking in Llanberis can be limited during peak times, so plan accordingly.
Glyn Rhonwy will be the official parking for athletes and spectators. The car park will open at 5:00am and close at 8:30pm. Parking will be a £7.50 donation for the day. All proceeds will go to a local community group.
There are also numerous pay and display car parks located in Llanberis. Please make sure you buy a ticket because you are very likely to get booked if you don’t!

Llanberis offers a range of accommodations to suit various preferences. Given that it is a small countryside village with limited convenience often found in large cities, it's advisable to choose lodging that aligns with your dietary needs, as dining options may vary. Some establishments provide full meal services, while others may offer only breakfast or be entirely self-catering. For those looking to self-cater, local supermarkets are available in the village.
Here are some accommodation options to consider:
Please be aware that parking vans overnight in Llanberis car parks, especially the 'Lagoons' and cars or vans in residential roadside locations causes disruption for the local community and bad feeling toward events. Please ensure that you park considerately and find accommodation in recognised locations. Sleeping in vans or cars overnight is not allowed in Llanberis car parks.
Please book your accommodation early as all hotels will be booked well in advance of the race weekend. Please mention the XTERRA Trail Run World Championship or Snowdonia Trail Marathon Eryri when booking your stay.

Each course includes three timed segments:
These segments will be clearly marked with signs indicating the start and end of each section. Timing is automatically tracked, so there’s no need to do anything extra—just run your race and give it your best effort through each zone.
How it Works
Whether you're a climbing specialist, a smooth strider, or a fearless descender, the Segment Challenge gives you the chance to shine—no matter where your strengths lie.
You must close any gates you pass through, irrespective of how you find them.
Where there are stiles along the route be prepared to queue up and wait to cross. Any runners found to be jumping fences or walls will be disqualified from the race. Please use good race etiquette - First come, first served.
Any person found littering will be immediately disqualified from the event and banned from all XTERRA and Always Aim High Events. Please respect the beautiful location you are running in and dispose of any litter responsibly. Litter and gel wrappers can be disposed of at the designated litter points or handed to an event marshal along the route. Be especially careful when opening gel wrappers, as the tops can easily become separated.
All competitors must attend the compulsory safety briefing in the start area on race day 15 minutes before your race start time.
Remember the Ultra Trail Marathon, Full Trail Marathon, the Half Trail Marathon and the 10K Trail Race take place in a mountainous environment, and at times you will be in remote areas.
Furthermore, there will be rough technical sections in some areas. Therefore, you must be vigilant at all times. In the spirit of trail running, please keep a lookout for your fellow competitors.
Half Marathon, Marathon, and Ultra distances must be prepared to carry the mandatory kit detailed in the Pre-Race Info section
