The Corrida das Areias begins and ends at Infantry Regiment No. 10 in São Jacinto, Aveiro. This 12 km race for adults combines road and sand, deviating from a typical city circuit.
Most of the route is within the RI10 grounds, with a notable stretch crossing Praia de São Jacinto along the beach. Infantry Regiment No. 10 organizes the event, receiving technical assistance from Ria Ativa. A solidarity walk accompanies the main race.
