ESP
Sergio is a swimmer from Spain, a sprinter, whose official competitive record spans 12 seasons and 138 meets.
His recorded career begins in 2014, and one of his earliest marks still on file is the 100 breaststroke in 1:33.87, raced in Gijón. He started out alongside C.N.CIUDAD DE OVIEDO.
His signature event is the 100 backstroke, the event he has raced the most, followed by the 200 backstroke and 50 backstroke. Backstroke is where his specialisation lies (67 meets), while freestyle appears in more meets (69 meets and 89 recorded swims spread across 6 different distances) because he races it across the full distance range rather than as a main event.
His fastest 100 backstroke stands at 58.83, set in long course (50 m) at Palma de Mallorca.
The record runs unbroken from 2014 to 2025: 12 consecutive seasons without a single missing year. 2023 is the busiest season on record, with 47 verified individual swims.
Those meets span 8 different venues (Oviedo, Gijón, Sabadell and Palma…). He has raced for C.N.CIUDAD DE OVIEDO.
The last race on record is dated November 23, 2025 in Gijón, with 2 swims: 30.81 in the 50 breaststroke and 2:09.64 in the 200 backstroke, all in short course (25 m) and 1 PB improvement. He closes this record with 31 current event personal bests and 268 all-time PB improvements, across 314 verified official swims in competitions governed by RFEN.
