About the race
The Yr Wyddfa Ultra 100 is a 102 mile mountain ultramarathon through Snowdonia Eryri National Park with 5,172 m of ascent, 150 places and a 42 hours race cut off. The route runs from Betws-y-Coed and passes Beddgelert, the Snowdonia Slate Trail and the Nant Gwynant valley, including sections near Sygun Copper Mine, Llyn Dinas and Llyn Gwynant. The event uses live online GPS tracking and is organised as a self navigation race with 11 checkpoints along the course. Checkpoints provide refreshments, vegetarian and vegan options, hot food at some indoor locations and basic medical cover.
Checkpoint cut off times are strictly enforced and participants must attend every checkpoint and have their details recorded. Pacers are permitted from Checkpoint 6 only and must carry the mandatory kit. A finisher buckle is awarded by finishing position: Gold for the top 100, Silver for places 101–200 and Bronze thereafter. Entrants must be at least 20 years old, in good health and have completed an organised 50 mile ultramarathon before race day.
Mandatory kit must be carried at all times; examples include a hardcopy map, compass, waterproof coat and trousers, headtorch (min 75 lumens), backup light (min 25 lumens), survival bag, two base layers, 1 litre water capacity, emergency rations (min 500 calories), whistle and the provided GPS tracker. Dropbags are allowed at two designated checkpoints with a 50 litre size limit. Alternative low level route options may be used in adverse weather.
