Well organised race, with brilliant on the ball staff and great atmosphere. The Ultra had a good array of textures and terrain on track and trail, with some technical and wet patches, but still accessible to novice distance runners.
Looking forward to returning next year.

Awesome event, the atmosphere on both days was fantastic, staff were friendly and helpful as were the other runners. The scenery was breathtaking and the route itself was cheeky yet really good going. I will 100% be doing this again!!!

ROUTE
This is one tough Half Marathon with over 1192m of ascent most of which is up Wales’ highest peak. The hills start almost immediately as you climb up through Llanberis and then Maesgwm, also known as Telegraph Valley. Turning left onto the Snowdon Ranger Path you have a further steep climb up before crossing the railway, reaching the Finger Stone and starting your descent down the Llanberis Path. The views, all the way to Anglesey, are incredible, but don’t get complacent you haven’t finished yet! Once back down at the road in Llanberis you are diverted through the woods past Dolbadarn Castle with the sting in the tail being the final climb up the infamous Zig Zag path and into the quarries. Reaching the top of Vivian Quarry you’ll be able to see the event village and the finish line down below and better yet, it's pretty much all downhill to the finish from here.
AGE
You must be at least 17 years old to take part in this race.
START
The Half Marathon usually starts at 09:00 though this is subject to change. The race start time will be confirmed in your Final Instructions which are available to view on the website 10 days prior to the race.

This beautiful route shares the same start as the marathon, leaving Llanberis via Maes Gwm, before descending into Nant-y-Betws, with stunning 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!

ROUTE
The Ultra Trail Marathon route leaves Llanberis via an ascent of Maesgwm with continued views of Yr Wyddfa (Snowdon), before dropping down towards Rhyd 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 Yr Wyddfa, to the Finger Stone, via the PyG track. Once at the Finger Stone runners will descend 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.
AGE
You must be at least 20 years old to take part in this race.
START TIME
The Ultra Trail Marathon usually starts at 06:30 though this is subject to change. The race start time will be confirmed in your Final Instructions which are available to view on the website 10 days prior to the race.
