Attendees come prepared to show elegant to the other guests, customers, entrepreneurs ....

On the other side of the beach, a plastic net mark where the safety distance must be removed bathers minutes before each race. On the beach the atmosphere is festive, people come prepared for a long afternoon of racing and there is a curious custom in which the protagonists are the youngest of the families.
