Overview

• Donostia Arraun Lagunak dominated the first women's tanda in 10:29.20, with Tolosaldea second at +10.00 and Orio third, setting the order for the tanda de honor.
• Zierbena was credited with the men's day-one lead after Orio was docked three seconds for having two support zodiacs in the restricted zone, with both crews breaking 19 minutes.
• Coaches highlighted exceptional speed, with Zierbena's time described by Dani Pérez as the third-best mark ever recorded in the competition.
• The men's tanda de honor will feature Zierbena, Orio, Urdaibai and Donostiarra, while Getaria, Hondarribia, San Juan and Lekittarra race in the other final.
• Calm seas and shifting wind put a premium on lanes and splits, as large crowds packed Paseo Nuevo and the port for the season's showcase regatta.
