Triathlon de Siedlce is a 28 km triathlon in Siedlce, Poland’s Masovian Voivodeship. The race is set around freshwater, green space, and a relaxed local atmosphere. It takes place in early summer, suitable for athletes seeking a complete swim-bike-run day without an overly formal or exclusive atmosphere.
The course utilizes Siedlce’s lakes, ponds, and extensive greenery, offering a setting that feels more like a brief sporting excursion than a demanding city race. Families can participate fully, with children’s and junior races offered alongside the main event. Following the races, attendees can explore nearby attractions such as Ogiński Palace or the Cathedral of the Immaculate Conception, relax in Aleksandria Park, or enjoy a terrace in the city center.
