Andersenrun La Mezza tra le Baie is a FIDAL-certified competitive half marathon held in Sestri Levante, on the Ligurian coast near Genoa. The race begins at 8:30 AM from the athletics track in Parco Mandela, returning to the same location for the finish. Participants have 3 hours to complete the 21.097 km distance. The field is limited to 500 athletes, making it a more intimate event.
The course consists of two laps of a 10.6 km circuit. Starting from Parco Mandela, the route proceeds towards Riva Trigoso, passing the church of San Pietro. It then loops back towards Sestri Levante via a narrow carugio, featuring a notable passage through Baia del Silenzio. Here, runners will cross a temporary walkway situated near the water. Entry is open to adult runners holding the required FIDAL registration or recognized foreign club membership. The event is organized by Atletica Levante in conjunction with the municipality of Sestri Levante.
