Downhill Swim

The Downhill Swim follows the Oulankajoki river in Finland, offering two competitive courses of 12,000 and 24,000 meters. Participants navigate the current throughout the event, which is scheduled annually in early August. Swimmers are transported from Ruka village to the designated start points, traversing the protected waters of Oulanka National Park until they reach the finish area. Registration typically opens in late September for the following summer, and the event requires a solid level of swimming endurance rather than specialized racing experience.

The river environment

As you swim, the surrounding wilderness of Kuusamo presents a landscape shaped by both nature and history. The water moves through a region where Finland’s four large predators—brown bears, wolves, lynxes, and wolverines—inhabit the forest, though sightings remain uncommon. Near the riverbanks, you may spot eagles and swans. The terrain is marked by remnants of human activity, including stone-age artifacts that have been unearthed along nearby shorelines. Further into the region, the park's geography features the dramatic Kiutaköngäs rapids, where the water drops over 13 meters, a site that once recorded extreme winter temperatures.

Historical context of the region

While navigating the river, the endurance required for the long-distance courses reflects the resilience of the local history. During the 1944 Lapland War, church bells from 1698 and 1721 were hidden in the local cemetery to prevent their seizure by Soviet troops; they remained buried for fifteen years until their location was disclosed by a returning German commander. Today, the event relies on organized logistics, including mandatory shuttle services, to manage the transit of athletes and spectators through these sensitive natural zones. Participants are expected to adhere to strict outdoor regulations while within the national park boundaries, ensuring the preservation of this river corridor.
