Defi Wind: 1000 windsurfers in Gruissan

One thousand windsurfers from 25 countries will line up at the start of 2014 Défi Wind, in Gruissan, France, between 23rd-25th May.

The 14th edition of the Défi Wind is sold out. On the largest windsurfing marathon in the planet invites sailors to experience one of the most famous winds of the world: the Tramontane.

The Tramontane is a strong, dry cold wind that blows from the north to the Gulf of Lion. It accelerates as it passes between the Pyrenees and the Massif Central, as a result of the Venturi effect.

The Tramontane is similar to the Mistral in its causes and effects, but they are two different winds. Both come from the same atmospheric configuration and have much the same effects.

However, the mountain corridors they follow are different: the Tramontane passes between the north of the Pyrenees and the Massif Central. The word "tramontane" dates back to the 13th century. It was taken from the Italian "transmontana" and was originally used to designate the North Star (transmontana stella: "the star from beyond the mounts").

The event will be run alongside the Défi Kite (29th May - 1st June), in its second edition, with 150 kiteboarders speeding up for record times. Both events will attract world champions, sporting legends and a large number of amateurs.
