The Cold Half Marathon Swim is a 15km winter marathon swim on Hong Kong Island from Stanley Main Beach to Deep Water Bay Beach. This is a solo or 2-person relay race. 

For those who love swimming in the chill but mind the extreme distance, you can sign up for the 1.5km Cold Plunge race. This is the only winter swimming event of its kind in Hong Kong. 

Medals and prizes for top 3 category and age-group winners. Your entry also includes professional chip-timing, race swag, post race food, and award ceremony.

There will be category prizes for all three races. 

The event is jointly organised by AVRA and 26 Coaching, and sponsored by Streamline Sports.

Points to Note

Limit to a maximum 30 solo swimmers due to limited availability of safety support. A motorboat or a kayak & support paddler is mandatory for 15km solo swimmers.

There will be two start times. If your estimated finish time is over 4.5 hours, please select the earlier start. You may be penalised if you choose the early start but complete in under 4.5 hours. 

For relay teams there are two options:

  • 30/30 - A change is mandated at every 30 mins
  • Half/Half - There is one change only at the 7.5km point

A support motorboat is mandatory for all 15km relay teams. A “Yak” relay(paddle/swim) may be accepted for relays, upon the organiser’s assessment of race day temperature and condition. For Yak Relay teams, a wetsuit is mandatory and inflatable kayaks/support craft is not permitted. 

Since swimmers will either have a support boat or a kayak, swim buoys are not mandatory for the Cold Half.
