Youth world windsurfing champion in 2016, winner of 4 consecutive wingfoil World Cups between 2022 and 2025, and Formula Wing title holder in 2025, Mathis Ghio knows the sea as a demanding arena of passion. Now, he is also using his visibility to protect it.

30 metres from the finish line, plastic joins the race

During a competition in Turkey, a large plastic bag brought his board to a dead stop while he was leading the race, just a few metres from the line. It was a meeting as brutal as it was unexpected with the pollution he regularly observes at his spots.

“That's when you realise that plastic pollution is not a distant or theoretical subject.”

The same taste for concrete solutions

A student at INSA Lyon, Mathis identifies with our approach: deploying adapted tools, measuring their results, and acting with local communities. In competition as well as on social media, he wants to raise awareness among water sports enthusiasts and encourage other athletes and partners to get involved.

Along with Louis Margot, Yves Courbon, and Théo Masse, he enriches a community of ambassadors who carry our message far beyond the collection zones.
