The second event for the Winter Series is next Sunday, June 12.
The river challenge will be held on October 29-30, with the Saturday being the 200m Olympic distance sprints - which, like the Winter Series, can be entered by six-person waka ama, four-person flat water kayaks, and quad rowers, along with surf lifesaving canoes and surf boats.
There are also the three "Plastic Funtastic" races, which are open to families and corporate teams.
Sunday is the big one - the feature 13km river challenge under four bridges down the river, as well as a 4km, two-bridge race for all man-powered craft and the new 10km big boat and small boat races.
The River Challenge also includes a "Cash 4 Clubs" competition - where all clubs accumulate points for every entry on the weekend and every placing in a race.
The club with the most points at the end of the events will pick up a cash prize.
Entries are now open.
