The UKWA One Hour Classic Challenge at Calshot

Ready to put your windsurf or wingsurf skills to the test? The SUP Co x Calshot is proud to play host to the Duotone x The SUP Co One Hour Classic on 14th & 15th June 2025, an exciting weekend of racing, fun and camaraderie in one of the UK’s most iconic watersports locations.
Whether you’re a seasoned competitor or new to the start line, the One Hour Classic is your opportunity to experience an exhilarating challenge against the clock, in a relaxed and welcoming environment. Run in partnership with Duotone and the UK Windsurfing Association (UKWA), this event is all about community, performance and having a blast on the water.
What is the One Hour Classic?
Simple in format but big on energy, the One Hour Classic sees riders complete as many laps of the course as possible in one hour. It’s a true test of strategy, endurance, and board speed. And with racing open to both windsurfers and wingsurfers, it’s a unique chance to share the water and push yourself in good company.

Calshot Spit is a legendary location on the South Coast, renowned for its wind reliability and flat-water racing potential – ideal for this kind of timed format. And as one of the very few places that works brilliantly in a northerly breeze, it’s the perfect setting for this early summer spectacle.
