One thing's for sure, Reidy loves to put on a good event, and there's no shortage of giveaways, celebrities and quirkiness.
You can choose from 1km, 2.5km and 5km swims, and the event is open to participants 16 years and over on the day.
While you're in Rose Bay, take a walk along the foreshore walkway, grab a coffee at Sugar & Spoon Cafe, Ministry of Coffee, or take it up a significant notch by booking a table at the Catalina Restaurant.
The 1km course starts at the boat ramp at the Woollahra Sailing Club and makes its way north across the bay to an apex buoy and then returns to the start/finish at the boat ramp.
For those taking on the 2.5km swim, you will cross the bay north, like the 1km swimmers, but then take a slight dogleg left to follow the shoreline towards Hermit Point. From there, you'll turn and head back along a similar line back to the start/finish.
5km course swimmers will do two laps of the 2.5km course.
While you're there
Located right at the start/finish is the Woollahra Sailing Club, who will be open for breakfast, including delicious bacon and egg rolls. You'll be able to toast to your successful swim from 10am, and presentations will be from 11.45am.
For good coffee pre and post swim, head to Sugar & Spoon or Ministry of Coffee, both located in Lyne Park.
Travel and parking
Parking isn't too bad in the area if you get there early enough. Free parking is available on New South Head Road and in the Lyne Park carpark (just watch the time limits on some parks).
The Rose Bay ferry sails in and docks at the park, so that's a fantastic option for those coming further afield. Check ferry timetable. Buses also run up and down New South Head Road from Bondi Junction and the city.
