Hoffer Triathlon Działdowo takes place on a Sunday in Działdowo, featuring both solo participants and relay teams. The event provides two shorter long-course distances: 1/4 Ironman and 1/8 Ironman, suitable for those seeking a challenging multisport competition without the commitment of a full-distance triathlon. This event is organized by the Hoffer company in collaboration with city and county officials, and it is noted as the second edition held in Działdowo.
The competition begins with a swim in an artificial lake, followed by a very fast cycling course. The bike segment concludes at the Działdowo stadium, leading into a run through city streets towards Malinowo. The finish line is also located at the Municipal Sports and Recreation Center stadium, establishing a central point for transitions and viewing. Competitors are listed as coming from various Polish locations, such as Mińsk Mazowiecki, Malbork, Kwidzyn, Gdańsk, and Warsaw.
