MULTI LAP COURSE
A Course Designed for Support, Safety, and Spectator Fun
25KM, 10KM, 5KM, 3.5KM, 2.5KM, 1KM, 500M, 200M AND 100M COURSE
We're using a multi-lap course for most events, creating a spectator-friendly layout that keeps the action close to shore. This setup allows for maximum support from friends, family, and fellow swimmers, while making it easy to combine laps to suit all distances – from shorter swims to the epic endurance challenges.
The course also offers enhanced safety, making it easier for our experienced guards to keep a close eye on swimmers at all times – so you can focus on chasing your goals with confidence.
Cut off times for the 25km on Day 1 will be 10 hours, that's 2min 10 sec per 100m. Cut off for the 10km on day 2 will be 5 hours.

Swim caps & start groups
As part of your swim pack, you will receive a silicon swim cap. Each start group has a different coloured cap. Start groups are determined by the speed group you selected in the entry form. If you have swum with us already this season please bring your cap to minimise the number of caps you collect and reduce our environmental footprint.
The start groups are calculated by our operations team and are organised by speed groups & entry numbers. These can vary from event to event, unless you are a Multi Event pass swimmer, and we are reluctant to change these as it can affect results.

Speed 1: 1:20 - 1:30 per 100m
Speed 2 – 1:30 - 1:40 per 100m
