Southampton Half Marathon & 10K 2026

The Southampton Half Marathon, 10K & Junior race begins and ends next to Saint Mary's Stadium, providing a clear football-ground landmark from the start. This autumn city-street event offers three distances: a half marathon, a 10K, and a junior race. The half marathon starts first, the 10K follows later in the morning, and the juniors run around midday. The format suits runners aiming for a personal best, and it also functions as a family race day, as the shorter and junior options involve more participants. The half marathon course consists of two laps, the 10K uses one lap, and the junior race is one lap of Saint Mary's Stadium. The roads are described as smooth, with each kilometre indicated by distance flags and marshals positioned along the route to guide runners and offer encouragement. Entries include chip timing, complimentary race photos, post-race treats, and a themed medal, covering essential race-day provisions without exclusively targeting serious club runners.
