The Rat Race Sea to Summit - Yr Wyddfa on 27 September 2025 is part of a trilogy of trail ultramarathons to the high points of England, Scotland and Wales.

The Yr Wyddfa edition is on a 33 mile route starting from the coast at Caernarfon Castle then through stunning Snowdonia scenery towards Beddgelert on the much quieter and utterly dramatic southern side of the mountain. From there you will continue your ascent to the summit via the Watkins Path and the South Ridge before descending via the Ranger path. The finish line is Bron y Feds Uchaf, Rhyd Ddu.

The course is fully waymarked and takes place on public paths, shared access trails and live roads. It is 75% trail and 25% road.
