Our event format explained

Out of the total distance of 33.3km over a 4-day long weekend, you will swim between 6 or 7 swims, breaking up the full distance.

*The details of the final distance depend on multiple factors and are based on race management decisions at each event.

Below is a typical breakdown of an UltraSwim 33.3 event* (*subject to change)

Day 1

Is the ice-breaker. Our goal is to always break down the first day’s distance into two separate swims 5km or less. This gets a good chunk of the swimming out of the way and leaves you ready for what lies ahead.

Day 2

Is usually a longer than a 5km swim, which is then followed by an untimed (mandatory) distance of 2-3km where you can swim at your own pace or with your friends with no time pressure.

Day 3

Is marathon day, the queen of swims - a beautiful 10km. This is when we usually see swimmers perform at their best. Should you choose, your 10km swim can be MSF-ratified.

Day 4

Is the grand finale, we usually swim just over 5km, at the finish line gather all the swimmers, and together (with friends and family if you choose) we swim the final 250m to the final finish line together.

2km (non-mandatory) swim upon arrival

During most of our events, we offer a 2km non-mandatory swim upon arrival. This takes the pressure off the other days and allows swimmers to connect with one another.
