British long-distance swimmer and environmentalist Lewis Pugh swam the entire length of the Hudson River and arrived in Manhattan in about a month. Pugh started in mid-August at the source of the river in the Adirondack Mountains in New York State and then swam around 500 kilometers to the mouth of the river near Manhattan in the Atlantic Ocean, where he arrived, according to US media reports. With his campaign, Pugh wants to draw attention to the protection of the oceans shortly before the start of the UN General Assembly in New York.
It is not Pugh's first high-profile action. He has completed a long distance swim in all of the world's oceans and in 2007 became the first person to swim a long distance at the North Pole.
