Time flies when you're chasing speed. It’s hard to believe, but the Dunkerbeck Speed Challenge (DSC) is celebrating its 10th anniversary this year! What started as an online gathering of passionate windsurfers has grown into a global community of over 5,000 riders from all corners of the planet. From kids under 10 to legends over 70, the DSC proves that speed knows no age. As Björn Dunkerbeck says:

"Windsurfing keeps me young!"

And we couldn’t agree more.

Join the Celebration

Mark your calendars and get ready for another epic year of speedsurfing action! The 2025 DSC is once again split into three exciting periods:
