London, July 27 : A 22-year-old American kayaker has entered record books after plunging 186 feet over a waterfall in Washington State.

Tyler Bradt suffered just a sprained wrist and a broken paddle as he fell for four seconds over Palouse Falls, before reaching the bottom.

He fell down the raging torrent of water and landed 20ft under the water and stayed submerged for seven seconds before coming back on the surface.

"I have been passionate about running waterfalls for a while now," the Telegraph quoted Bradt as saying.

"I had come to a good understanding of what I believe I am capable of and what is possible.

"Palouse was a calculated decision to reach further into the unknown and make a dream a reality," he added.

Bradt had previously set a record in 2007 when he took a kayak over the 107-ft Alexandra Falls in Canada, but his feat was surpassed by a Brazilian rival went down 127-ft Salto Bello falls in Brazil. (ANI)
