Go from sea to mountains in this unique trail race ending in Eryri (Snowdonia) National Park
The spectacular Eryri 80K returns for the second year in the Eryri by UTMB programme, offering a tough and rewarding journey from coast to mountains. The 78km route climbs 2,500m, starting at sea level in Caernarfon before heading inland into the mountains in the heart of Eryri. The course links coastal paths, remote trails and high mountain ground, capturing the scale and variety of North Wales.
The race starts at 20:00 on Friday, sending runners out from the coast and into the night as they work their way towards the mountains. Finishers will earn 3 Running Stones, making them eligible for the Hoka UTMB Mont-Blanc lottery. Built for experienced trail runners, this is a race that demands steady effort, good judgement and respect for the terrain. A true test from the shoreline to the high peaks.
The top 3 runners will not get automatic qualification to UTMB World Series Finals.

Getting to the start
A free shuttle service will be provided by the organisation for runners operating from Llanberis to the start of the 80K race.
No reservation is required.
Departures will take place on Friday the 15th between 06:30 PM and 07:00 PM.
Eryri 80K runners will receive a 1 x 30 litre UTMB World Series drop-bag when collecting their race bib at the main event venue.
Drop-bags should be dropped at the start line in Caernarfon before the race start. The bags are then taken to the finish line.
Drop-bags should be collected after your race at the main event venue upon presentation of the runner's race bib. The Bag Drop marquee remains open until the end of the event.
Only UTMB World Series drop-bags can be used. Poles are not allowed in the drop-bag.
Aid stations are available at strategic locations and regular intervals along the course. These provide basic food and drink options and shelter from the elements.
Larger aid stations will be well stocked with hot food options, hot drinks and a selection of other snacks including cold drinks, water, cola and Näak Energy products.
There are toilet facilities at all locations (including women's toilets and toilets with period products). Most larger aid stations are located in existing buildings or marquees, are warm, and will have seating and rest areas.
Eryri 80K is a semi-autonomous / self-sufficient event with aid stations and medical cover at strategic locations on the course. However, due to the extent of the course we strongly advise you to have your own support crew. Your support crew will be able to provide you with personal assistance at designated locations. Due to the remote nature of some aid stations, and the lack of easily accessible car parking, we have to be very selective of which locations we can allow personal assistance.
We strongly advise you to have a supporter to drive you home after the event. Due to the fatigue of completing Eryri by UTMB, runners should not attempt to drive themselves home.
