XTERRA Snowdonia Trail Marathon Eryri 2025 Trail Running 10k


13 Jul 2025




Route Description

This beautiful 10k has something for all runners. The first 5.5k has a mixture of road, track and trail and takes in the beautiful lower slopes of Yr Wyddfa (Snowdon). It then passes across the valley dipping into the beautiful woodlands around Dolbadarn Castle before taking on the gruelling Zig Zags that take you to the top of Vivian Quarry. Once here it's down hill on stunning forest trails all the way to the finish line.
