River Taff and Long Wood

Route Overview & Local Insights

This 6km loop from Hailey Park is a quintessential Cardiff run, offering a perfect blend of fast, flat tarmac and technical riverside trails. Starting on the iconic Taff Trail, you'll enjoy a gentle 10m ascent on well-maintained surfaces that are ideal for finding your rhythm. However, the character of the run changes beautifully as you veer toward the Long Wood Nature Reserve and the old disused Glamorganshire Canal. Here, the path transitions to more natural, soft-surface terrain with occasional roots and dirt tracks, providing a refreshing challenge for your stabilizers while staying almost entirely level—ideal for runners looking for a scenic "half-and-half" experience without the bite of steep Welsh hills.

Steeped in industrial heritage, this area serves as a green lung connecting the city to the heart of the Taff Valley. As you run through Long Wood, you are tracing the historic route where coal was once transported from the valleys down to the Cardiff Docks via the canal. Now a protected Site of Special Scientific Interest (SSSI), the canopy provides excellent shelter from the wind and rain, making it a favorite year-round haunt for local runners. Keep an eye out for kingfishers and herons along the water; it is easy to forget you are only a few miles from the bustling city center while navigating this tranquil, leafy corridor.
