Tilbury Douglas Yorkshire Run for WaterAid 2026

The Tilbury Douglas Yorkshire Run for WaterAid is a 5K and 10K charity run held at Swinsty Reservoir, near Harrogate, typically in September. The course follows paths within the Washburn Valley, on the southern edge of the Nidderdale Area of Outstanding Natural Beauty. This event is organised in partnership with Yorkshire Water to generate funds for WaterAid's clean water and sanitation initiatives. The route is largely flat, featuring a single moderate incline, sections of road, and short, level dirt-track portions. This design accommodates both steady runners and those aiming for personal bests. The event is licensed by UK Athletics, allowing results to be published on Power of 10 and to be considered for local championship standings. All proceeds benefit WaterAid projects, such as efforts to provide clean water to 130,000 individuals in Ethiopia. Car sharing is encouraged through reduced entry fees and preferential parking due to limited space.
