Think wild West Coast beauty meets endurance adventure. The Geo Bay Cool Water Classic is a standout on the ocean swim calendar, a true bucket-list swim for those who love distance, depth, and the raw beauty of open water. Held in the pristine turquoise waters of Geographe Bay, this 20km ultra-swim offers more than just a physical test; it’s a journey of pacing, presence, and sheer perseverance.

With the stunning coastline of Western Australia as your backdrop, the course takes you along a stretch of protected bay known for its clean, cool conditions and sweeping views. Unlike your typical mass-start sprint, this is a more intimate, stripped-back event, designed for experienced swimmers who know that endurance swims are as much about mindset as muscle.

Whether you’re chasing a personal best, ticking off a milestone, or simply drawn to the adventure of a solo or relay challenge, the Cool Water Classic offers strong support throughout. You’ll be backed by your own paddler, guided by experienced event organisers, and surrounded by a tight-knit group of swimmers who understand what it means to push yourself that little bit further.

And the finish? It’s nothing short of magic. Salt on your skin, a wide stretch of sand ahead, and that deep, quiet pride that comes from swimming 20km in open water. It’s an achievement you won’t forget, and a day you’ll replay for years.

If you’ve been looking for your next big swim challenge, something to train for, build toward, and feel truly proud of, this is it. The Cool Water Classic isn’t just a race. It’s a rite of passage.
