TPSK 1925 · GER
Vandenhirtz, is a swimmer from Germany, an international traveller on the circuit and a national-level swimmer, whose official competitive record spans 6 seasons, 5 countries and 31 meets.
His recorded career begins in 2021, and one of his earliest marks still on file is the 400 individual medley in 4:34.66, raced in Berlin. He started out alongside TPSK 1925.
His signature event is the 200 butterfly, the event he has raced the most, followed by the 400 freestyle and 100 butterfly. Butterfly is where his specialisation lies (22 meets), while freestyle appears in more meets (23 meets and 56 recorded swims spread across 5 different distances) because he races it across the full distance range rather than as a main event.
His fastest 200 butterfly stands at 2:05.75, set in long course (50 m) at Berlin Swim Open.
His record includes national championships, between 2025 and 2026 (136th German National Championships, Berlin, GER and Dutch National Championships & European Trials, Eindhoven, NED). A representative mark at that level is 2:09.85 in the 200 butterfly, recorded in long course (50 m). He also appears in international meets.
The record runs unbroken from 2021 to 2026: 6 consecutive seasons without a single missing year. 2022 is the busiest season on record, with 38 verified individual swims.
He is a genuinely international swimmer: the official record spans 5 countries (Germany, Luxembourg, UNK, Belgium and the Netherlands), including 7 of 31 meets outside Germany.
Those meets span 14 different venues (Berlin, Wuppertal, Aachen and Luxembourg…). He has raced for Aachener Schwimmverein, Schwimmverband NRW, SG Frankfurt and TPSK 1925.
