The Tarell and Pen y Fan — 15 km Running Route

Embark on a challenging 15.2km adventure in the stunning Brecon Beacons, starting with a gentle 7km stretch on the Taff Trail beside the Afon Tarell. This initial flat section, on a mix of track and lane, offers a peaceful warm-up before the terrain shifts dramatically. Prepare for a substantial ascent, tackling grassy trails that become increasingly stony and eroded as you climb towards the iconic peaks of Corn Du and Pen y Fan, reaching an impressive 886m.

This demanding route, with over 600m of ascent and significant sections above 500m, is perfect for experienced runners seeking a serious workout and breathtaking views. While offering fantastic training for hill races and ultramarathons, remember to be well-prepared for rapidly changing weather conditions characteristic of mountain environments.
