There is also a public open trial on 4 August to allow the public to come play and try out the FloatFit AquaBoards. Come anytime between 10 am to 4 pm for this opportunity!

This year we are also a part of a programme of the Singapore University of Technology & Design (SUTD) student initiated competition called CRUX, Southeast Asia's only Deep-water Solo Event. Participants will scale a wall 8 meters high with a pool just below you to catch their fall! (Don't miss out the expletives as they fall!)

Not an experienced climber? Not to worry! There will also be a 4.5 meter boulder tower for the newly initiated. No prior registration will be required for the boulder tower!

We are truly happy to work with these students to bring greater value to participants of both events! Their insanity in climbing truly exemplifies the spirit of our athletes too!

If you are interested, by taking part in our event, all who sign up for our 4K Challenge will also be able to take part in their fringe activities for FREE!
