Lämmijärve ujumine

The 1895 Lutheran church in Mehikoorma stood as a sentinel over the water for nearly half a century, before falling to the destruction of 1944 during the Second World War. Today, its stone ruins remain near the shoreline, serving as a silent witness to the village's resilience while swimmers prepare to enter the same lake that shaped this landscape. These waters mark the narrowest point of the Peipus-Pihkva lake system, a 1.7-kilometer bottleneck known as Lämmijärv, or the Warm Lake, which acts as the vital connection between the larger northern and southern basins. Swimmers traversing this channel often find themselves passing over the remains of an ancient harbor, where a distinct pile of stones lies submerged just 63 meters from the current bank.

Navigating the Warm Lake

The character of this swim is dictated by the lake's shallow basin, which responds rapidly to atmospheric changes. While water currents typically remain mild—moving at a gentle pace of 5 to 9 cm/s—they are primarily shaped by the prevailing winds across the surface. During the spring thaw, a more consistent flow develops as water pushes from north to south, a phenomenon that has historically influenced navigation through this passage. As you sight your line, the 15-meter white ferroconcrete lighthouse of Mehikoorma serves as a primary reference point; erected in 1938, it remains the tallest of the three navigational markers on the lake and provides a clear silhouette against the horizon for those pushing toward the finish.

Organized by the MTÜ Palu puhkajate looduskeskus, this annual event brings the local community to the water's edge every August. The logistics are straightforward for participants, with the course focusing on the unique geography of this narrow transition zone. Because the lake is shallow, the water captures the summer sun effectively, allowing for temperatures that are often comfortable for long-distance efforts without the need for thermal gear, though competitors should always verify the specific event regulations regarding wetsuits before race day.
