Two days. One lake. Endless challenges.

Dive into the action at Swim Fest Lake Karāpiro, held on the world-class rowing waters of the Waikato. Framed by rolling green hills and fresh country air, Lake Karāpiro sets the scene for the biggest weekend of swimming in the Series.

From the mighty 25km ultra-marathon swim to the short and sharp 500m Blast, there’s something here for every swimmer. The littlest legends get their moment too, with the 100m and 200m Banana Boat OceanKids events bringing big smiles and plenty of support.

Want more? Build your own endurance weekend with back-to-back combos. Conquer the ultimate double, 25km and 10km for a massive 35km total, or mix it up with 5km and 3.5km on consecutive days. However you piece it together, Swim Fest is all about pushing limits and creating your own story.

Plus, if you’re part of the Banana Boat Ocean Swim Series, you’ll automatically be entered into the 3.5km main event, no extra steps required.

Whether you’re chasing personal bests, testing your grit, or just here for the atmosphere, Lake Karāpiro has it all. Big swims, big energy, and one unforgettable weekend on the water.
