Triathlon Gdynia 2026

Ironman 70.3 Gdynia begins with a 1.9 km sea swim from Gdynia Śródmieście Beach, concluding back on the city beach. This middle-distance triathlon in the Polish port city of Gdynia typically follows the standard 70.3 format: a sea swim, a 90 km bike ride, and a 21.1 km run. The event ranks among Poland’s largest triathlons, attracting both dedicated age-group athletes and professionals. Following the swim, cyclists embark on a 90 km bike course through Kashubia and near the Tricity Landscape Park, transitioning from the Baltic waterfront to regional rolling roads. The 21.1 km run returns participants through Gdynia, with spectators lining the course, before finishing on the sand-side city beach. The competition includes world-class triathletes at the front, alongside amateurs seeking a demanding, full-day challenge within a major event atmosphere.
