On Welcomes European Champion Jeanne Lehair
Zurich, Switzerland, September 10, 2026 — Swiss sports brand On is officially announcing the addition of European Triathlon Champion and World Triathlon Championship Series (WTCS) standout Jeanne Lehair to its global roster of elite athletes.
Born in Metz, France, Lehair was introduced to triathlon at age seven and quickly rose through the national ranks, becoming a European and World Mixed Relay Champion in 2015. In late 2022, Lehair made the career-defining decision to switch her national allegiance to represent Luxembourg—a move that unleashed a breakthrough stretch of form on the global stage and established her as one of the most explosive, tactical, and versatile competitors in modern triathlon. Known for her consistency across the swim, bike, and run disciplines, Lehair reached the pinnacle of European racing by winning Gold at the 2023 European Triathlon Championships in Madrid. She followed up this breakthrough achievement with a landmark victory at the World Triathlon Championship Series (WTCS) Yokohama, solidifying her rank among the top multisport athletes in the world.
The addition of Lehair strengthens On’s elite short-course triathlon lineup, joining a global roster that includes world-class athletes such as Kristian Blummenfelt, Kat Matthews, Gustav Iden, and Solveig Løvseth.
“Joining the On team is a huge milestone in my career,” said Jeanne Lehair. “On’s dedication to pushing the boundaries of athletic performance through technology and design aligns perfectly with my own drive to keep progressing on the global stage. As an athlete, having equipment and a team that believes in your potential makes all the difference. I’m thrilled to step into this next chapter powered by On’s innovation.”
“We are thrilled to welcome Jeanne Lehair to the On family,” stated Maria Ortega, Triathlon Athlete Manager at On. “Jeanne’s incredible consistency across all three triathlon disciplines, paired with her fierce competitive spirit and historic victories on the World Triathlon stage, makes her a standout talent in global endurance sports. We look forward to supporting her journey with our high-performance apparel and footwear as she continues to challenge the world's best.”
