Sea Swims ...

Each night there will be a short and a long course. The short swim will generally be 200m-500m, while the long swim will be 800m-1500m. Exact distances will vary depending on conditions.

Given the nature of these events and the challenges of tide and wave conditions, it is important that all athletes feel comfortable and confident swimming 500m front crawl in open water, whilst making significant forward progress at all times. Adherence to this requirement will be at the sole discretion of the race director.


Thursday Nights

The Nelson Summer Sea Swims are held each Thursday night (during the summer) at 6.00pm from the Nelson Yacht Club ramp on Wakefield Quay in Nelson.


Rylock Endurance

The Rylock Windows and Doors Endurance Series of four longer swims will provide an extra challenge, particularly for those swimmers targeting the national Ocean Swim series.


Endurance Series

We're looking for some volunteers to help (in particular on Thursday nights) - including Kayakers, Patrol Boat crew, First Aid and just general support!  So if you're available or know someone who is please drop us an email at info@nelsontriclub.co.nz.

"Sea swims have been held in Nelson over the summer on Thursday nights since 1987. For the first 20 years, the swims were organised by Peter Owen of the Nelson company Eyebright, and were known as the Eyebright swims. That historical link remains, with the annual Eyebright Mile, actually a swim of 2km."
