Vansbrosimningen

At the river confluence in Vansbro, the Vanån grants swimmers two kilometers of fast, current-assisted swimming before demanding a grueling one-kilometer haul upstream against the flow of the Västerdalälven. Vansbro is home to Vansbrosimningen, an open water swimming race held in the Vanån and Västerdalälven rivers in Dalarna, Sweden. The event traces its roots back to 1950, when Einar Anselius and Mats Qvarfot decided to promote open water swimming by tackling a long-distance route beneath all six bridges crossing the local waterways. What began as their local challenge has since evolved into one of Sweden's premier freshwater events, taking thousands of participants into the heart of Dalarna each July. The 3,000-meter race layout preserves that original river journey through town.

Swimmers dive into the Vanån to cover the first 2,000 meters downstream, moving with the river's current as it glides toward the meeting of the waters. The real test arrives at the confluence, where the course swings into the Västerdalälven for an arduous final 1,000 meters swum directly upstream against the oncoming flow. Water temperatures in early July typically hover between 16 and 22 degrees Celsius, giving the river a bracing feel that becomes especially noticeable once swimmers turn against the current of the main stem. Race day in the river is a bustling spectacle from the opening gun. Swimmers in past editions have described a crowded start packed with breaststrokers, requiring quick navigation and zigzagging to find clear water through the churning waves.

The downstream stretch in the Vanån often offers a forgiving tailwind and river assist, but turning upstream into the Västerdalälven can bring headwind, cold eddies, and river chop that test stroke mechanics to the finish. Any hesitation about the open river is quickly eased by the safety fleet, which lines the entire course with rescue boats and marshals spaced every ten meters, while cheering spectators crowd the riverbanks to urge swimmers forward.

Glacial eskers and river sediments along the Västerdalälven

The landscape framing the swimming course is the product of ancient glacial forces that shaped central Sweden. Within Vansbro municipality, prominent eskers of glacial gravel and sand flank the banks of the Vanån and rise through the terrain at Äppelboåsen. Along the Västerdalälven, where competitors battle upstream, the river has laid down broad belts of fine sediment.

Floating bridges and timber drivers on the Vanån

Long before swimmers adopted the rivers for sport, these watercourses formed vital arteries for human industry in Dalarna. Archaeologists have identified the remains of Iron Age iron production at approximately one hundred sites throughout the region, clustered predominantly along the Dalälven river system. The town of Vansbro itself owes its name directly to a historic floating bridge constructed over the Vanån river. In the centuries before railways arrived, the settlement was inhabited almost entirely by ferrymen and loggers who navigated the fast-moving currents. The Vanån and the Västerdalälven served as giant conveyor belts for the Scandinavian timber trade. That log-driving past remains closely woven into the town's character today. Visitors can explore the Sawmill Museum in Vansbro, which preserves an authentic timber worker's residence alongside exhibits that chronicle the history of the local timber and floating era.

The Gönan watercourse and native river wildlife

The rivers around Vansbro belong to a thriving aquatic ecosystem. The Gönan nature reserve encompasses the Gönan watercourse and Lake Gösjön. This protected river corridor shelters vulnerable freshwater pearl mussels alongside healthy populations of brown trout, European minnow, and bullhead. Wildlife thrives directly in the waters swum during the competition as well. The river Vanån offers a 30-kilometer run of prime freshwater habitat that supports wild fish, including river-dwelling brown trout, grayling, and northern pike.

The Vansbro riverfront from seasonal floods to calm waters

Vansbro has always maintained a close relationship with water. In earlier eras, this low-lying confluence exposed the settlement to severe seasonal flooding. That historic risk was permanently resolved with the completion of a three-kilometer protective embankment in 2020. The barrier shields the town center from rising water levels. During race week, this landscaped riverfront provides an ideal grandstand for spectators watching swimmers fight their way up the Västerdalälven. Visiting the river banks is simple and inviting for travelers and traveling supporters. The river Vanån is easily accessible by road, allowing visitors and anglers to reach the water's edge in rubber boots without requiring wading gear. Whether cheering from the grassy banks, tracing the downstream current, or diving into the cold push of the Västerdalälven, swimmers meet a race that celebrates Sweden's living river heritage.
