One day at the shores of the Limmat river…

Ready (with the green turtle) , steady …

… and go! The 51th swim through Zurich started!

Professionals completed the 2 km track in 12 minutes…

… despite sharks …

… and dark tunnels…

.. the turtles brought even us to the end … in just one hour …

by cool floating 🙂 In-water pictures shot with Olympus TG-1, dry pictures with Nikon D800.
