The Mitja Marató + 10K “Ciutat de Tarragona” begins and ends by the port and the Maritime Promenade, establishing a city-and-sea setting from the start. The primary event is a 21.097 km half marathon, with a parallel 10K that follows much of the same route and shares the race atmosphere. The half marathon is one of Catalonia’s oldest and most traditional, and the event also features children’s races by age group near the finish area.
The half marathon follows a single-lap road circuit through Tarragona’s main streets, the port area, and the Roman core of ancient Tarraco. Runners pass the Roman Amphitheatre and imperial walls, with sections of the route within a UNESCO World Heritage site and elevated parts offering views over the Mediterranean. The course includes long straights for consistent pacing, along with some climbs between the lower port area and the city center. Rambla Nova is the loudest point on the route, where many local spectators gather to encourage runners through the busiest section.
