I am finding some information about Qiongzhou Strait crossing. It seems to be an established marathon swim route, with solo swims and also races taken place. However, what I can find are only news articles, and I can't find any information on the web about the races, sanctioning organisation, etc. (According to some news articles, the sanctioning organisation is called 海口海牛横渡俱乐部, but I can't find any contact information of it)
Qiongzhou Strait is the nearest channel to the place where I live with established marathon swims taking place, and I would like to use that as the starting point for me to try out channel swimming, like people in the U.K. doing the English channel, or people on the U.S. west coast doing the Catalina Channel.
Does anyone know how I can attempt a Qiongzhou Strait crossing, either an independent swim or a race?
P.S. My family is from Hainan, and I am trying to ask my mum if she knows anything about it from my relatives there.
