Participants can choose between an Ultra 50 km distance or a shorter Trail 25 km version, both heavily off-road or mixed terrain. The course winds through the parks, canal tow paths, riverbanks, and green spaces of Ealing, including a climb up Horsenden Hill with views across West London. The event is organised by We Run Ealing and aims to showcase the borough’s greenery while offering a tough but scenic challenge for runners and walkers. Checkpoints with water are placed along the way, runners are encouraged to be self-sufficient (bring their own reusable cups or bottles), and there’s a strong community/support atmosphere. It’s London’s only ultra that is wholly contained within a single borough.
Organized by krono:sports ltd, the 50 km ultra is held in Ealing, London on Saturday, 24 May 2026. This single-loop trail course takes runners through Ealing’s parks, blueways, greenways, tow paths, and trails—an urban-meets-countryside challenge showcasing the greenery of the borough.
Also part of krono:sports ltd’s Queen of the Suburbs Ultra, the 25 km trail starts on the same date—22 March 2025—in Ealing, London. It follows a similar route to the 50 km but shorter, offering a scenic challenge through parks and trails for those wanting a less extreme distance.
