The organisation committee and the water police decide together on the Monday before the event whether the Seeüberquerung will take place. For safety reasons, the weather must be nice and dry (no wind, no storm) and the water temperature in the middle of the lake must be at least 21°C. The maximum number of participants is limited to 9000.

The route is marked with buoys. Lifeguards are stationed on boats at least every 75 metres. If you get tired: swim to the nearest boat. In case of emergency: use the distress signal > slap the water with an outstretched arm. The water police control shipping activities. Ships only cross at the marked lock shortly after the start. Be careful around the ship lock – short waiting periods are possible. Helpers on pedalos inform the swimmers before the ship lock in good time. Swimming safety rules by SLRG
