Enter our Whacky Races! Bring your inflatable steed and join in with our splash and dash across
the pool. You could win a fab swimming backpack courtesy of Zoggs.
For those creative swimmers, enter our fancy hat competition. You can craft your own ahead of the party, or join Southsea Crafty Club to make yours on the day.
The theme is 'Portsmouth's 100th birthday' and we encourage you to use upcycled materials. Wear your hat in our fancy hat parade - but
remember - this includes swimming a length of the pool, so it'll need to stay on while you swim. There will be gorgeous Drybones hats to win for the best in show.
