Challenge yourself in the mountains of Eryri (Snowdonia) National Park
The Eryri 100K is a formidable journey across the northern mountains of Eryri National Park, offering an "alpine-scale" ultra experience in North Wales. Beginning in Llanberis, participants set out on a course that is both beautiful and technical. The route immediately immerses runners in the rugged grandeur of the region, tackling some of the most prominent peaks and climbs.
As the race unfolds, you will be treated to epic views from iconic summits and challenged by trails that includes technical scree, rocky paths, and even a bit of scrambling. You will navigate through stunning landscapes, passing by glacial lakes and through remote valleys, where the sheer scale of the mountains becomes apparent. The course, while scenic, is designed to test every aspect of an ultra-runner's physical and mental fortitude within a 30 hour time limit. With relentless elevation gain and selected runnable sections, the Eryri 100K is a true mountain odyssey.
PRACTICAL INFORMATION
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.
Villages which the route passes through include:
- Dolwyddelan
- Blaenau Ffestioniog
- Betws Garmon
Eryri 100K 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 taken to the Bag Drop before the race start. The bags are then taken to the Gwastadanas Aid Station.
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.
Eryri 100K 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.
