And they'll be facing a formidable pair like Macarena Campomanes and Catalina Castillejo, who boast ten titles between them. These two players from Puerta de Hierro even won together twice (2016 and 2017), giving them an edge. Add to that their experience on national teams and in top-level individual competitions, and you have a duo of immense consistency.

On the other hand, Madrid native Mónica Jessen and Canary Islander María Castillo have the opportunity to win for the third consecutive time (they did so in 2023 and 2024). Their proven teamwork will be a strong asset this week.

They also have winning experience in the tournament: María de Orueta and Rocío Ruiz de Velasco, winners in 2021.

The tournament, as is customary, is held over two days. The first day consists of 18 holes played in Fourball format, and the second day consists of another 18 holes played in Greensome format.
