The Semi-Marathon de Santander is a city road race held in Santander, on Spain’s Cantabrian coast, with the next edition scheduled for mid-October. It features a full half marathon of 21.0975 km, a 5.5 km race, and separate children’s and junior courses, ensuring participation for runners of all levels. Its slogan, “Discover the city by running,” reflects the event's focus on using Santander itself as the backdrop, keeping participants within the urban environment. The route winds through the city and along the seafront, showcasing beaches and streets that highlight Santander's appeal as a running location. Competitive runners can choose the half marathon, while less experienced runners and families have shorter distances available within the same event. The surrounding Cantabria region offers additional attractions for visitors: the Palacio de la Magdalena is located in Santander, with Cabárceno Natural Park, the Altamira caves, and the Picos de Europa being feasible day trips from the race location.
