Trainers / Eksperts / Coaches

It is a good idea to make use of a swimming coach. During a crossing like SwimÖresund, it can be decisive with a good open water coach, specialized in sea swimming. Here you can get swimming programs designed for marathon swimming and get help and coaching in this particular area.

The coaches offer courses for swimmers of all levels. The course can take place via telephone and online meetings and depending on where you are in the world, there is also the possibility of physical 1:1 meetings or group sessions.

If you need to improve your swimming technique, coaches can analyze your arm strokes and your general swimming technique with a professional eye. In this way, you ensure that you are in the best possible position in the sea. You may want to have someone video your swimming style and then upload it to the coach for feedback.

Working with a coach will not only make you a more efficient and faster sea swimmer, but also prepare you mentally for the big challenge.

In addition to hard work, commitment and dedication, you also need to work on your willpower and mental attitude, so that you can, for example, better withstand the cold and other challenges along the way.

Remember that it is important to find a swimming coach with whom you have good chemistry and with whom you can work well together towards your goal. After all, you are writing history 😊
