Shu Pu is one of the event coordinators of the Cold Half, an extreme 15 km winter marathon swim in Hong Kong Island held on February 23rd 2013.
The Cold Half 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. 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 rotate every 30 minutes with motorized escort required. Swimmers will start at Stanley Main Beach and finish at Middle Island Beach with a barbeque and warm-up dinner held at the Royal Hong Kong Yacht Club in front of Hong Kong's only fireplace. There are 2 categories in the Cold Half: Naturally Ocean and Wetsuited and Buoyant.
