If you haven't come across it yet, there has been a new informative website on the subject of "swimming" for a few weeks - http://www.swim.de/
On it you will not only find everything you need to know about perfect technique and the latest material, but also training plans of the professionals: http://swim.de/training/trainingsplaene
Whereby you don't have to implement Thomas Lurz's 9.8km program 1: 1 😉
The site is operated by the triathlon publisher spomedis, so it is more oriented towards open water swimming and therefore very interesting for all triathletes! Check it out, it's worth it.
have a beautiful Sunday!
