Overview | CourseRegistrationResultsVideoPhotos

The Clean Half Extreme Marathon Swim is a 15km course and Asia’s longest for an Organized event.  It is also Asia’s only team really event, so most competitors are in teams of 5 people.  Support boats are provided.  Solo swimmers must be expert swimmers and submit their previous race accomplishments over 5km, with times, to verify their proficiency.  No wetsuits are used due to the perfect water temperature.  For those interested in cold-water challenges, you can swim in our Cold Half Extreme Marathon Swim which is the same course but in January or February with colder and more extreme conditions. Not for the faint-hearted.
