Gdansk Half Marathon

GARMIN PÓŁMARATON GDAŃSK is a sea-side race weekend built for runners who want a proper half marathon (21.0975 km) with a big-event hub and extra formats for friends and family. The 2026 edition runs 26–27 September in Gdańsk, centered around Polsat Plus Arena Gdańsk, which hosts the weekend activities and makes logistics (expo + bib pickup) straightforward.

The main event is the individual half marathon plus a 4-person relay option, so you can either race solo or split the distance as a team.

Saturday is where the weekend gets its “festival” feel: Nocna Piątka (Night 5K) is staged as a new, more spectacular night format, with runners moving through illuminated streets and strong spectator energy—ideal as a standalone race or a fun warm-up before Sunday. Kids’ races (Junior Gdańsk) also take place on Saturday, making it easy to travel as a group with mixed goals.
