Andover Half Marathon & 12K 2026

The Andover Half Marathon & 12K begins and ends in Andover town centre. The half marathon starts on the historic High Street. This October running event in Hampshire offers two distances: a 13.1-mile half marathon and a 12K option, the “Half of the Half” loop. Seasons Run Club organises the races, providing chip timing, way-marked courses, marshals, checkpoints, and aid stations along the half marathon route. The half marathon is mixed terrain, predominantly road, with approximately 84% paved surface and around 229 metres of elevation gain, distinguishing it from a flat city race. The course proceeds south of Andover through tranquil villages, offering views of three Iron Age hill forts before concluding back in the town centre. The half marathon has a 3-hour 30-minute cut-off time. All half marathon finishers will receive a bespoke medal. The first male and female overall finishers earn cash prizes, and age-category awards are also presented.
