III Sopocki Maraton Pływacki

Arriving in Sopot by train, the coastal landscape shifts from industrial outlines to the refined silhouettes of the Baltic resort town. The sea air hits as you walk toward the municipal beach, a place where history and sport collide. As you prepare for the 5km or 10km event, your eyes inevitably drift toward the Grand Hotel Sopot. Built in 1927, this structure remains a beacon of the interwar era, standing watch over the starting line. Swimming here is a direct link to the legacy of Jean Georg Haffner, the former Napoleonic medic who pioneered this coastline as a premier health destination in 1823. His vision shaped the very environment where you now prepare to dive in.

The depth and the legacy

Once in the water, the scale of the Bay of Gdańsk becomes clear. With an average depth of 50 metres, dropping to 118 metres, these waters have supported coastal fishing for centuries. As you push along the coastline, about 200 metres from the shore, you are effectively navigating the space that once separated the Polish Republic and the Free City of Danzig, marked historically by the nearby Swelinia brook. This is not just a swim; it is a passage through a terrain that has seen shifting borders and royal visitors, such as when the Sierakowski Mansion—formerly known as the Swedish Manor—hosted Polish kings like Augustus II the Strong.

Race day logistics

Organized by the Sopockie WOPR, the event requires participants to be self-sufficient, specifically regarding safety buoys, which are mandatory. The 10km race starts at 7:00, while the 5km begins at 9:00 near the Gdynia-Orłowo pier, a different start point that adds variety for those seeking a longer challenge compared to the shorter local pier-loop swim. The entry fee of 300 PLN covers your timing, a finisher medal, and a post-race meal. Keep an eye on the Sopot Lighthouse, which serves as a visual guide, and watch for the wooden Sopot Pier that stretches over 500 metres into the bay. If you feel the pull of the coast, remember that the Grodzisko stronghold rests just inland, a constant reminder of the centuries of activity this bay has witnessed.
