Southampton Marathon
Southampton, Hampshire, England, United Kingdom
Southampton Marathon is a road race through the city whose previous routes have included the waterfront, St Mary’s Stadium and the Itchen Bridge. The 2027 course is still to be confirmed, so earlier maps should guide expectations without settling them. Bridge climbs have featured before; save detailed pacing decisions for the final route. Standard entry and charity options are available through the organiser, with separate results and photographs for the marathon and the festival’s shorter distances.
