Washburn Valley and Timble Ings

Route Overview & Local Insights

Tackling this 31.3km loop from Blubberhouses is a rewarding challenge that showcases the best of the Washburn Valley’s diverse terrain. This long-distance route links the "Three Reservoirs"—Swinsty, Fewston, and Thruscross—offering a mix of flat, fast-paced reservoir circuits and rugged, undulating forest tracks. Runners will transition from the manicured, well-maintained paths surrounding the lower waters to the more technical, muddy trails near Thruscross. The inclusion of Timble Ings provides a sharp contrast, introducing a significant climb through thick coniferous woodland where the footing becomes more irregular and the heart rate climbs along with the elevation. With over 300 meters of ascent, it’s a fantastic endurance builder for those looking to test their legs on a mix of soft woodland mulch and gravel tracks.

The Washburn Valley is steeped in North Yorkshire history and serves as a vital artery for the region's water supply, but its roots go much deeper than the 19th-century reservoir construction. While running alongside Thruscross, keep an eye out for the remnants of the West End village, which was submerged when the valley was flooded; parts of the flax mill and stone bridges occasionally reappear during dry summers. The area is also a haven for local wildlife, and as you push through the quiet, sheltered stretches of Timble Ings, you’re likely to spot Red Kites soaring above the tree canopy. This route manages to feel remarkably remote despite its accessibility from Harrogate and Otley, making it a favorite for Yorkshire trail runners seeking a long-run escape into the "Little Lakes District."
