Mini Maraton Koper — Aquapark Žusterna

Gliding through the waters off Žusterna, you might find yourself tracing the faint, submerged outlines of the ancient stone channels that once carried fresh water to the city. These 16th-century wooden and stone pipelines, long since reclaimed by the sea, serve as a silent reminder of how Koper, once an island, secured its survival against the salt. As you look toward the shoreline, the horizon is dominated by the 14th-century bell tower of the Cathedral of the Assumption, its historic bronze bell cast in 1333 still marking the rhythm of the city. For those seeking a longer endurance challenge, the competitive circuit continues just a few days earlier with the 16th Biserov Swimming Marathon, while those looking for a different coastal perspective a week later might consider the Trieste Open Water event.

The course and the history

The Mini Maraton Koper, hosted by PK Koper, invites swimmers to tackle a 1,100-meter course in the Bay of Koper. This stretch of water carries stories far older than the modern port; local tradition traces the city’s origins to 524 AD and the arrival of Bishop Nazarius, while the ancient name Aegida is tethered to the myth of the shield of Athena falling to earth. As you navigate the buoy line, you are essentially swimming through a landscape shaped by both maritime industry and deep-rooted mythology. The nearby shell dune of Ankaran, a unique geological feature formed after 1990 from the silt of the expanding port, stands as a stark contrast to these ancient legends, showcasing the modern transformation of the Slovenian coastline. Throughout the event, the focus remains on the local swimming community, with participants often reflecting on the legacy of figures like the local military diver Spartaco Schergat, whose history is deeply intertwined with these coastal waters.
