HuleSvøm Bornholm

HuleSvøm Bornholm is an annual open water swimming event hosted by Copenwater, taking place in the sea around the Danish island of Bornholm. The event offers participants a variety of challenges with distances of 2000m, 2500m, and 4000m, typically held in August. The water environment is characterized by its rocky coastline, including notable features like the caves near Hammerhavn, locally referred to as the 'wet and dry ovens'. Swimmers navigate between granite cliffs and natural harbors, such as Vang and Svenske Havn, encountering varied conditions that range from flat, calm stretches to sections with active currents and swells. The logistics are managed by Copenwater, providing guided routes and support for swimmers exploring these coastal waters. Historically, the event has focused on group-based exploration of the island's unique geological formations, with routes adjusted based on the prevailing sea conditions and wind. The coastal landscape, marked by dramatic rock formations and remnants of old stone-loading harbors, provides a backdrop for the swim. During the event, participants may encounter marine life such as jellyfish and seaweed, which are common in these Baltic waters. The experience is centered on the rugged nature of the island’s shore, with routes often involving transitions between open water and sheltered natural inlets.

Race day logistics

The event structure emphasizes safety and navigation, with guides providing updates on conditions prior to entry. Participants should be prepared for varying water temperatures, which can be brisk even in late summer, and the need to manage their energy during segments with tidal or wind-driven currents. The swim follows a coastal path, often incorporating short land-based treks between different swimming sections, such as the route between Svenske Havn and Pærehavn. The logistical support includes designated safety personnel, ensuring that swimmers can navigate the challenging, rocky environment effectively. While the distance options provide flexibility, the core of the event remains the collective experience of traversing the coastal waters of Bornholm, supported by local organizers who coordinate the daily schedule based on the weather forecast.
