This is a wonderful swim, right in the heart of Copenhagen. If you've ever seen Borgen, it goes around the parliament and central government buildings in a circular route. There are waves every five minutes or so, there's lots of different abilities in each wave, so lots of overtaking going on, but plenty of room to do it in.
There's a fantastic atmosphere around the start with lots of support around the course, and supporters can follow you around, apart from one part which was underground because of metro works.
All in all, this is one to savour and enjoy rather than race around, and a rare chance to swim in clean waters in the heart of a capital city.
Water relatively warm for Copenhagen, as was about 30 celcius on the day.
