The "Half Marathon", FIDAL race in natural environment, opens the "Sea and Mountains" events. The course runs along the De Andrè waterfront bicycle trail, crosses the coast of Cogoleto and runs along the seafront of Europe to the Nautilus of Varazze, where the boa reappears to return to Arenzano. The landscape is one of the most striking: it runs a step away from the cliffs, in a vegetation with typically Mediterranean features.
