Snowdonia – Autumn Crossing

We’re back at our brand new location on the shores of Llyn Cwellyn nr Rhyd Ddu in the heart of Snowdonia. Set at Bron Fedw Uchaf farm on the quieter side of the mountain range our new routes will give you a chance to explore the less popular trails in the area.

The Autumn Crossing gives you the opportunity to run the Spring Crossing but in reverse. The route will head out towards the mountain ranges and forestry’s to the west with the most spectacular sea views. You will climb Moel Hebog, Y Garn and the Nanlle ridge to name but a few.

We have distances from 13k – 55k to choose from and all will test your abilities and mental strength. This is by far our hardest race on our calendar so please check the routes before you enter, after all this is Snowdonia.

Price for marathon and ultra now includes gps trackers for all runners.

The 13k route is canicross friendly (please ensure your dog has trained for the event). The half, marathon and ultra routes are not.
