Cold Half Divisions

The Cold Half is either a solo race or a 2-person relay. If performed as a relay, a support paddler is required. If performed as a relay, the swimmers can either rotate every 30 minutes or can swim half of the distance. A motorized escort or carbon neutral option is required.

Cold Half

The Cold Half is a 15 km extreme winter marathon swim in Hong Kong Island in February by Open Water Asia. The Cold Half (or the Cold Half & Cold Standard Extreme Marathon Swim) is modeled after Asia's most popular marathon swim, the Clean Half, except the water temperature is more to the liking of marathon swimmers, channel swimmers and adventurists of various types than the water temperatures during the Hong Kong summer. The expected water temperature is 20-21ºC (68-69.8ºF) with an expected air temperature that can range from 12.7-22ºC (55-72ºF). The swimmers will also encounter The Wall, a body surfing section in the middle of the course. It is one of Asia's Top 50 Open Water Swims and part of the Cold Standard.

It also includes the YakSwimmers who consists of 2 relay swimmers who rotate with each other for 30 minutes each using 1 kayak the entire way of the 15 km Cold Half marathon swim.
