The fight for category promotion could hardly have had a more complicated start. In the first leg against FC Ona Sant Adrià, the Catalan team managed to win 4-1, facing the eliminator with great positivity. But then, the epic arrived.

After a time of absolute equality, the promotion would be decided in the penalty shootout in which Mendiburu became a heroine by managing to stop the decisive shot and engrave the name of Real Sociedad B in the list of teams that will be in Primera Federación Iberdrola in the 2026-2027 season.
