Marta is a swimmer from Spain, a backstroke specialist and an international traveller on the circuit, whose official competitive record spans 14 seasons, 2 countries and 143 meets.
Her recorded career begins in 2013, and one of her earliest marks still on file is the 50 breaststroke in 53.29, raced in Colegio Lledo. She started out alongside C. AQUATIC CASTELLO.
Her signature event is the 100 backstroke, the event she has raced the most, followed by the 200 individual medley and 200 backstroke. Backstroke is the backbone of the whole record: 76 meets and 161 recorded swims.
Her fastest 100 backstroke stands at 1:05.03, set in long course (50 m) at Castellon.
Her record includes international meets, in 2021 (Xv Trofeo Internacional Ibercaja Ciudad Zaragoza--xii Memorial Eduardo Lastrada). A representative mark at that level is 39.87 in the 50 breaststroke, recorded in long course (50 m).
The record runs unbroken from 2013 to 2026: 14 consecutive seasons without a single missing year. 2022 is the busiest season on record, with 61 verified individual swims.
She is a genuinely international swimmer: the official record spans 2 countries (Spain and UNK), including 10 of 143 meets outside Spain.
Those meets span 15 different venues (Castellón, Palma, Málaga and Sabadell…). She has raced for C. AQUATIC CASTELLO, CLUB DEPORTIVO NADOS CASTELLON and CST-CST COSTA AZAHAR.
