Hector Valdivieso Claramonte

Cst-Cst Costa Azahar · ESP

Hector is a swimmer from Spain, a sprinter and an international traveller on the circuit, whose official competitive record spans 9 seasons, 2 countries and 78 meets.

His recorded career begins in 2018, and one of his earliest marks still on file is the 1500 freestyle in 20:07.37, raced in Vinarós. He started out alongside Cst-Cst Costa Azahar.

His signature event is the 100 butterfly, the event he has raced the most, followed by the 200 individual medley and 50 butterfly. Butterfly is where his specialisation lies (50 meets), while freestyle appears in more meets (52 meets and 73 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 butterfly stands at 58.11, set in long course (50 m) at Sabadell.

His record includes national championships, between 2023 and 2026 (X CAMPEONATO DE ESPAÑA ALEVIN, Madrid, ESP and Campeonato de España Primavera, Sabadell, ESP). A representative mark at that level is 58.36 in the 100 butterfly, recorded in long course (50 m).

The record runs unbroken from 2018 to 2026: 9 consecutive seasons without a single missing year. 2024 is the busiest season on record, with 57 verified individual swims.

He is a genuinely international swimmer: the official record spans 2 countries (Spain and UNK), including 6 of 78 meets outside Spain.

Those meets span 5 different venues (Castellón, Sabadell, Valencia and Madrid…). He has raced for Cst-Cst Costa Azahar.

Still active: the directory includes official activity in the 2026 season. The last race on record is dated July 26, 2026 in Sabadell, with 1 swim: 58.11 in the 100 butterfly, all in long course (50 m) and 1 PB improvement. He holds 34 current event personal bests and 236 all-time PB improvements across 262 verified official swims in competitions governed by RFEN.
