About the race

On the morning of the KotlinRace, the docks of Saint Petersburg hum with a quiet, focused energy. Swimmers, their support crews, and the organizers from the Grand Swim team gather at the yacht club, checking currents and finalizing nutrition plans before being ferried to the start line in the Gulf of Finland. This annual 25km marathon, stretching from the Northern Capital toward the island of Kotlin, has become a milestone for long-distance swimmers across Russia. The event requires significant logistical precision, including mandatory support boats and pre-race medical screenings, which explains the high entry requirements and the 10-hour time limit. The first 3 kilometers offer a helpful push from the Neva river current, but once out in the open gulf, the water behaves according to unpredictable winds and tides, turning the swim into a true test of navigation and endurance.

Historical Waters and Hidden Depths

As you navigate the route, you are essentially crossing a massive, submerged timeline. The floor of this gulf is one of the world's largest ship cemeteries, hiding over 5,000 objects including 2,500 ships and 1,500 aircraft, preserved perfectly by the cold, low-salinity environment. While the surface looks expansive and serene today, these waters have dictated the fate of empires. In 1256, Alexander Nevsky led his army across the frozen gulf to launch raids against Swedish territories, a stark contrast to the summer temperatures of 16-22°C that you will face during the race. As you approach Kotlin Island, the fortifications of Kronstadt rise from the horizon, once dubbed the 'Russian Dardanelles' for their strategic role in controlling the waterway to Saint Petersburg. You will pass the haunting silhouette of the Plague Fort, an oval structure that functioned as a high-security bacteriology lab until 1917, a grim reminder of the scientific battles once fought behind its walls. The proximity to these historic markers serves as a constant mental anchor, grounding the physical exertion of the 25km distance in centuries of maritime legacy. Whether you are a soloist or part of an relay team, you are continuing a long tradition of crossing these currents, culminating in the pride of adding your name to the Honour Board on Kotlin island.

How to get there

Where to stay

Many participants prefer staying close to the yacht club to simplify their pre-dawn logistics on race day.

Things to do nearby

Beyond the race, the region offers deep cultural and active exploration. Visitors can tour the naval cathedrals of Kronstadt, a site of immense architectural interest, or delve into the history of the Sestra River mouth, where Neolithic settlements dating back 9,000 years were discovered. For active recovery, the gulf's coastline is ideal for SUP and kayaking sessions, while the surrounding forests provide tranquil trekking paths. Local cafes near the docks offer traditional seafood and hearty regional dishes perfect for post-race replenishment.
