Swanny Swim Thru is including a SUP division once again this Saturday morning at Cottesloe. Registrations are open until 4.59pm this arvo. Not sure if it's the same this year but in at least one of the previous years prizes have only been awarded for those registering online i.e. no prizes if you just rock up on the day. Its not especially cheap and is only 2.2km but can be a fun race/sprint and looks to have a following wind (although probably not enough to be a "downwinder").
