The Trail Events Co are back at our stunning location on the shores of Llyn Cwellyn nr Rhyd Ddu in the heart of Snowdonia (Eryri). Set at Bron Fedw Uchaf farm on the quieter side of the mountain ranges our new route, will give you a chance to explore the open mountains around Snowdon, before summiting Snowdon on your last climb before the decent to the finish. We have distances from 15k – 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. All routes summit Snowdon itself, be it near the start or near the finish of your chosen distance. If you choose the 55K option, we feel safe saying this will be the toughest 55k event you’ve done in Snowdonia! But all distances are tough, with lots of elevation and technical running. This year prices include personal gps trackers for each runner in all distances. We will have our event partners with us in the event village, Ellis Brigham Mountain Sports and UCAN UK along with out event caterers. Camping is available. Please note this event unfortunately is not canicross friendly.

This event is part of TEC Eryri The Crossing.
