Chloé and Matthieu Witvoet have begun their swim across the Atlantic from Cape Verde. They hope to reach Guadeloupe in three months, taking on a challenge that combines sport and environmental advocacy.
It has already been two weeks since Chloé and Matthieu Witvoet entered the waters off Mindelo, Cape Verde. Partners in life, they will now spend nearly three months swimming in relay, attempting to reach Guadeloupe powered solely by their arms. Their route: 3,800 km across the North Atlantic. Their goal: to set two world records — the longest swimming relay and the longest female-led crossing with drift. They alternate sessions in the water while the sailboat Papagayo ensures their safety. On board, they eat, rest, and plan each stage. The boat has been following them since their departure from Marseille on September 21, with its crew keeping a close watch.
Accompanied by 100,000 Students
But this challenge is not just about sport. Chloé and Matthieu are also swimming to raise awareness. Their journey is being closely followed by 100,000 students through an educational kit they initially designed for 50,000 children. Participating schools receive weekly content about the ocean’s role, pollution, climate, and marine biodiversity. The ambitious project aims to integrate ocean protection into school curricula.
If all goes according to plan, they will reach Guadeloupe in just under three months. Along the way, they will navigate kilometers of currents, unexpected events… and send educational messages to the classrooms following them. An inspiring expedition for everyone tracking their journey from school.
