On each night there will be a short and a long course. The short swim will generally be 300m-800m, while the long swim will be 1000m-1500m. Exact distances will vary depending on conditions. Where possible, the short course swim will extend to longer distances in the new year.

Starts will be in waves:

  • Short swim (orange caps).

Long course (3 separate waves)

  • Strong swimmers starting first (1-white caps)
  • Confident swimmers in wave two (2-green caps)
  • Recreational swimmers in wave three (3-red caps)

Less confident swimmers are asked to start at the rear of wave two or three. Kayakers will endeavour to keep a closer watch on these swimmers, who will also be in view of a shore official at all times. Choose these options if you enjoy the company and security of the series environment, but are not concerned about competition or times (times will be taken however as this is a check that all swimmers are accounted for).

Times will be adjusted to reflect the wave start, so you’ll receive your exact swim time. However, it’s important that you verify your wave start on registration and have the correct coloured cap.

Adherence to this requirement will be at the sole discretion of the race director.
