Southampton Half Marathon & 10K October 2026

The Southampton Half Marathon & 10K starts and finishes by Saint Mary’s Stadium, providing a clear football-ground base on the edge of the city centre. This is an autumn road-running event featuring a half marathon, a 10K, and a juniors race. The longer races begin in the morning, with the juniors running around midday. The half marathon covers two laps, while the 10K is one lap. Runners follow a straightforward city-street course with distance markers in both kilometres and miles. Marshals are stationed at key points along the route. Chip timing and free race photos are included. The finish area hosts an event village offering food, drink, partner goodies, medals, and an optional event T-shirt.
