The Snowdonia Trail Marathon consist of four different events:
- Ultra Marathon: 59.8k
- Trail Marathon: 27.3 Miles
- Half Marathon: 12.9 Miles
Arguably one of the UK's most challenging trail races, all four races will experience the the truly spectacular surroundings of Snowdonia National Park.
Perfect for all runners, the 10k route is a mixture of road, track and trail, and takes in all the stunning lower slopes of Snowdon. The route then takes runners across the valley, dipping into picturesque woodlands around Dolbadarn Castle, before enduring the gruelling zigzags taking you to the top of Vivian Quarry. From here, it's all back downhill to the finish line along stunning forest trails.
Boasting over 1192m of ascent up one of Wales' highest peaks, this is one tough half marathon. Right off the start line the route tackles some hills up Llanberis and then Maesgwm, better known as Telegraph Valley.
From here, the route turns left onto the Snowdon Ranger Path for another steep climb. Once reaching the Finger Stone, runners can enjoy the mountainous views along the descent back down the Llanberis Path.
Once back at the road the route diverts through the woodlands past Dolbadarn Caslte with the sting in the tail being the final climb up the infamous Zig Zag path and into the quarries.
Once at the top of Vivian Quarry, the event village is in sight, and its all downhill to the finish from here.
If you're looking for a challenge...you're in the right place. Ascending 1,685 metres over 27 miles of iconic and spectacular trails, this epic race will circumnavigate and eventually climb Wales' highest peak - Snowdon.
This beautiful route show off Wales' stunning trails, panoramic views, and tough climbs, and truly display why Snowdonia National Park is a mecca for outdoor enthusiasts.
The route visits Rhyd Ddu, Beddgelert, Nant Gwynant, Pen y Pass and Snowdon (via the PyG Track to the Finger Stone) before descending to the finish line along the Llanberis Path.
The Ultra route starts alongside the Marathon route up to Maesgwm with epic views of Snowdon. From here, the route drops down towards Rhydd Ddu and travels towards Beddgelert Forest.
From here, the Ultra breaks from the Marathon route to explore the beautiful Cwm Tresgl and Cwm Pennant. Next, runners will rejoin the Marathoners along Afon Glaslyn and Llyn Gwynant to the ascend up Snowdon to the Finger Stone via the PyG track.
A welcome descent down Snowdon along the Llanberis Path awaits as runners race down to the finish line. A paradise for trail runners, theres mountains, forest, stone paths, slate quarries, and tracks to keep you motivated the whole way.

Brilliantly brutal event. Nothing prepared me for "running" up a mountain. The "path" up was anything but, I'd call it scrambling although I'm sure experienced people wouldn't! One you must do, but probably only once! The aid stations were pretty poor with only fruit and gels at some stations. This would have been very basic for a normal rod marathon let alone a tough one that took me 8hr30 - the guys and girls doing the ultra would have had the same.

Buzzin’,as I ended up on the podium! 😉. Had my folks and wife with me to witness my greatest achievement yet. The set up was fantastic,everyone was super friendly,would definitely go to another event by Always Aim High 👊.
5.0Did the Half Marathon in 2019
A stunning route with a mix of challenges. Very well organised and route is well marked out. My knee went quite early on so I had to walk the final 13miles!The climb up to the summit is beautiful, busy with walkers also but we just pushed them off the mountain (joke!). We were very fortunate with the weather, it wasn’t too hot or too cold, I ran the whole race without the need to pull on a long sleeve top or remove layers. The aid stations are well placed out but I strong recommend ensuring you can carry at least 1 litre of water plus electrolytes, I found I was refilling my bottles at the final 2 (or 3 aid stations). Fantastic support from spectators or walkers passing by, the marshalls were very friendly and encouraging too - big up to Beddgelert Marshall ‘Sean’ for walking the final mile with me. A very painful downhill descent and finally crossing the line in 8hrs 15mins led to a very emotional finish, but so worth it!
