Dalesrunner 40

Semerwater, United Kingdom • 13 Sep 2025

DalesRunner 40 is the dramatic finale of the DR series, set in Semerwater, Raydale, North Yorkshire. The roughly 42 km (26.2 miles) course rises over 3,000 feet of ascent on hard-packed trails with a few boggy sections, demanding strategy, stamina and steady navigation. The route starts with a long climb toward Stalling Busk, then follows a scenic stretch of the Dales Way along the River Wharfe, skirts Roman roads and Weather Fell, and returns via the Cam High Road to Semerwater for a fast finish. In 2025 the course is largely unmarked; competitors get a tracker and GPX trace, with marshalled road crossings, recce events, and an optional DR40 Ultra extension to about 30 miles. Post-race Nav4 hospitality completes the event. Visit the organization's website for the most recent information.
