The city of Setúbal has hosted since 2006 a stage of the FINA Open Water World Cup, and has already held two Olympic Qualifications of the discipline. It is therefore considered the "sanctuary" of the Open Water in Portugal, where we can find excellent conditions for its practice, with crystalline and challenging waters.
The Mass Event is a competition open to all interested parties, who are over 14 years of age at 31-12-2017.
This event will be played in the same venue and along the same course of the FINA/HOSA 10 km Marathon Swimming World Cup, at a distance of approximately 1660m, equivalent to 1 lap to the 10km circuit of the main event. With the goal of providing a sporting experience of excellence, allowing the interested parties the privilege of swimming in one of the great stages of the sport world-wide in the last 10 years.
