XTERRA Snowdonia Trail Marathon 2023 Trail Running Ultra Marathon
The Snowdonia Ultra Trail Marathon encompasses 2199m of climbing over 57km. This beautiful route shares the same start as the marathon, leaving Llanberis via Maes Gwm, before descending into Nant-y-Betws, with sunning views over Llyn Cwellyn and Beddgelert Forest. The Ultra breaks off through the forest to visit the beautiful Cwm Tresgl and Cwm Pennant, before rejoining the Marathon Route in Nant Gwynant to ascend the slopes of Yr Wyddfa (Snowdon). Finally, you are rewarded with a 7km descent to a heroes' welcome back at the Event Village in Llanberis!
The Ultra Marathon is a UTMB Indexed race and will earn finishers 3 ITRA points.

The Ultra Trail Marathon route leaves Llanberis via an ascent of Maesgwm with continued views of Snowdon, before dropping down towards Rhydd Ddu. Upon reaching Beddgelert Forest the Ultra route breaks away from the Marathon route to explore the beautiful Cwm Tresgl and Cwm Pennant. Rejoining the Marathon Route, the Ultra works its way along Afon Glaslyn and Llyn Gwynant to the ascend of Snowdon, to the Finger Stone, via the PyG track. Once at the Finger Stone runners will descend Snowdon by the Llanberis Path all the way to the finish line. This route is a trail running enthusiast's paradise; with mountain, forest, stone path, slate quarries and tracks it isn’t hard to keep motivated the whole way around.
