The routes
The swimming course
The swim takes place on a 700-meter rectangular course marked with buoys in Lake Olbersdorf. The start is on the north shore. The start and finish area is located on the shore, approximately 30 meters from the water's edge.
The competition will be held in 6 starting waves, according to the respective distance and event. The longer distances result from multiple laps of the 700m course.
The information in the current race announcement is definitive. The organizer reserves the right to change or reschedule start times up to the moment of the competition. For safety reasons, weather-related delays, interruptions, or even cancellation of the race may be necessary.
Medical support is provided both on land and on the water. Participants who require help or assistance in the water should signal this with a clear hand signal.
Time is measured at the start and finish; for distances where more than one lap must be swum, lap time is measured at a buoy.
