The WSLSC WOW Challenge 2024 – Date to be confirmed

Watch this space for our announcement of the 2024 biggest swim challenge in Melbourne this summer – at Williamstown.

The Williamstown Open Water Championship – “The WOW Challenge” is Victoria’s world class, championship distance, open water swim event. The WOW Challenge is for everyone – champions, weekend warriors, kids, multiclass, fast, slow, young and old!

Past winners at Williamstown include 2015 World Champion Jordan Wilimovsky, Team USA’s Katy Campbell, Australian Dolphin Sam Sheppard and Brazilian Olympian Lisandra De Carvalho.

The WOW Challenge is swum at Williamstown Beach on our famous championship 2.5Km course. This year we have a beach start,  you will swim in an anti-clockwise direction.   Your first turn will take you around the Rock Groyne and over The Crystals, a local diving and snorkelling site. A left turn close to the boat harbour takes you out into deeper water and after another left turn, you’ll head East onto the legendary WOW Back Straight. With a final left turn, swimmers head back to the beach area, feeding station or finish arch on the sand.

Weather conditions may see the course reversed back into a clockwise direction.  We want you to have any wind behind you on the back straight.

The event is conducted by the Williamstown Swimming and Life Saving Club. Swimmers of all ages and abilities will have the opportunity to choose from a range of swim distances.

The WOW Challenge provides the chance to swim with the best swimmers from around the world, is part of the Great Victorian Swim Series and raises funds for not-for-profit organisations.

All  distances, wetsuits are permitted without restriction. Supplied event caps are compulsory. Fluro vests may be worn by choice. No other buoyancy or assistance tools may be used.
