This year, in this exceptional situation that the whole world is experiencing with all the travel limitations that are being imposed on us, we are happy to continue with the competition format to stay motivated and find more windsurfer for the speedsurfing discipline.

Because it’s also our main motivation to mobilize the entire windsurfing community and regain relative normality through our sport as soon as possible using current technology to compete together from any country in the world without traveling, while promoting windsurfing as an ecological sport and healthy lifestyle.
