[edit] 2012 Inaugural Event

The inaugural event kicked off at 11:30am, an hour later that scheduled due to thick mist brought on by the light westerly wind. The conditions were ideal. Almost zero wind forecast for the day, a 1.5 to 2 meter swell running resulting in some nice surf at the start, but once through the surf the sea was flat. Water temperature 13°C, and once the mist lifted a clear sunny day with a air temperature forecast of around 22°C.

24 swimmers jumped in, escorted by SUP, surf paddlers and canoes. The fastest time was 2:30:29 and the slowest time was 4:08:34.

[edit] Medical Report

As part of a research project carried out by Sean Gottschalk, all swimmer's pulse and body temperatures were taken at the start and end of the swim. There are three reasons for doing this:-

1) Safety - ie. checking swimmers temps before and after helps with assessment of hypothermia.
2) Athletes' individual data - to help swimmers get a better understanding of their own physiological changes in the cold water.
3) Pooled data - Putting everyone's data together to see the changes in the group as a whole, and compare individuals to the average.

2012 Results:-

Average Pre / Post Race Temperature 36.8°C / 33.7°C. Average drop in temperature: 3.1°C
Average Pre / Post Race Heart Rate: 73/min / 94/min. Average change: 21/min
Average swim time: 3:17:00
Average Water temperature: 13°C
