6k Run Harefield: Scenic Riverside Journey from West to South

Route Overview & Local Insights

This 6.4km loop through Three Rivers offers a refreshing mix of tranquil waterside paths and gentle undulating terrain. Starting in West Harefield, the route takes you along the scenic Grand Union Canal towpath toward South Harefield, providing a flat and fast paved surface for the first half of your run. As you head back via the Hillingdon Trail, the course introduces a bit of a climb with 33m of ascent, making it an excellent choice for runners looking to build stamina without being overwhelmed by steep inclines. The loop is largely paved, making it a reliable option for all-season training while still delivering that escape-into-nature feel.

Harefield is a hidden gem for London-edge runners, situated where the Grand Union Canal meets the beautiful Colne Valley Regional Park. This area is steeped in industrial history, once serving as a vital artery for trade between London and the Midlands, but today it functions as a peaceful green corridor. As you navigate the Hillingdon Trail on your return leg, you’ll be running through part of the "Great Barn" landscape, an area known for its historic timber-framed structures and lush wetlands that provide a vital habitat for local kingfishers and herons. It is the perfect spot for a weekend morning run followed by a coffee in one of the village's traditional pubs.
