The Semi-Marathon de Matosinhos is a half marathon held in May in Matosinhos, a seaside resort town in Portugal’s District of Porto, located just outside Porto. The primary race follows the standard 21.097 km half marathon distance. The event also includes a non-timed 7 km walk for those who prefer to enjoy the coastal route without the pressure of racing.
The half marathon follows a straight path along the Atlantic coast, featuring no elevation gain. While the course is flat, coastal winds can still affect runners' times. This race is suitable for participants aiming for a personal best, recreational runners seeking a manageable challenge, and walkers who appreciate sea views, Portuguese sunshine, and the proximity of the waves.
