Open water swimming — UltraSwim 33.3

UltraSwim 33.3 event’s aren’t just about the swimming, the camaraderie, world class services and stunning locations separates us from your regular swimming events.

The extremity of swimming 33.3km over four days is an experience that nothing can compare to. The feeling tense anticipation charges the start line every day as the swimmers prepare to take on this extreme challenge.

But the distance isn’t everything. Ultraswim 33.3 events are distinguished by a sense of intense camaraderie, friendship and pride.

Some swimmers have swam the distance before and some have never. We have a system where those who have swam an UltraSwim 33.3 event before have a droplet marked onto their swim hats. This allows the more experienced swimmers help those who are having last minute doubts. The transfer boats are a prime example of this, the air is full of mixed feeling, some excited, some terrified. Yet there is always a huge grip of positivity from the swimmers, staff and volunteers.
