5k Run Porthclais: Captivating Coastal Loop from St David's

Route Overview & Local Insights

This 4.7km loop offers a quintessential Pembrokeshire running experience, striking a perfect balance between accessible paved surfaces and breathtaking cliffside views. Starting from Pen-y-Garn and heading toward the picturesque harbor of Porthclais, the route transitions into a coastal spectacular as you sweep around the St Non’s Cliffs. With a manageable 55m ascent, the "hilly" sections provide just enough elevation to get your heart rate up without being overly technical. Runners will enjoy a fast, mostly paved terrain that makes this an ideal choice for a coastal tempo run or a scenic recovery jog while soaking in the Atlantic sea spray.

Steeped in Welsh history, this area is the legendary birthplace of St David, the patron saint of Wales. As you run past the ruins of St Non’s Chapel, you are passing one of the most sacred sites in the country, overlooking the rugged beauty of St Brides Bay. The Porthclais area itself was once a busy merchant port serving the cathedral city of St Davids, and the old stone harbor walls still stand as a testament to the region's maritime heritage. Whether you are chasing a personal best or simply enjoying the sunset over the jagged Ramsey Island coastline, this route connects you to the deep spiritual and natural history of the St Davids peninsula.
