Due to the complexities and permissions of organising a 100 mile race through Eryri, we are still working on the exact course for 2026. The maps and elevation profile will be revealed in the coming months.
UTS 100M is a journey into the wild, rugged heart of Eryri (Snowdonia). The race begins and ends in the village of Llanberis, nestled at the foot of Yr Wyddfa (Snowdon), the highest peak in Wales.
From here, participants will ascend through stunning landscapes, traversing technical trails and exposed mountain ridges. The route takes you deep into Eryri National Park, a land of mythical beauty. You will encounter the epic, jagged peaks of Eryri's highest mountains, descend into scenic valleys carved by ancient glaciers, and pass tranquil lakes like Llyn Gwynant and Llyn Idwal. Runners will navigate a diverse and challenging terrain, from rocky scree fields and boulder-strewn paths to boggy moorland, all set against a backdrop of breathtaking, untamed scenery and features of the historic slate industry.
This is a race that promises not just a physical challenge, but a complete immersion in a landscape that is both beautiful beyond belief and savage beyond reason.
Your mandatory kit (clothing and equipment) will be checked when you arrive at registration to collect your race bib and at the start of your race. You will be asked to show all of the kit requirements for your competition and have these items inspected by a member of the Event Team.
If you do not have an item of clothing or equipment which is mandatory for your race, you will not receive your race bib, will not be allowed to compete, and will be disqualified from the race
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:
- Capel Curig
- Dolwyddelan
- Blaenau Ffestiniog
- Croesor
- Beddgelert
- Rhyd Ddu
- Betws Garmon
UTS 100M 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 Ultra-Trail Snowdonia by UTMB, runners should not attempt to drive themselves home.
