Watch the moment Brazil’s answer to Bear Grylls runs for his life when a nature show goes wrong

THIS is the moment when things went wrong for a TV show host who was forced to leg it when nature got a bit too close for comfort.

Brazil’s answer to Bear Grylls, a documentary maker called Richard Rasmussen, was forced to run for his life when things took a sudden turn for the worse whilst filming a nature programme.

Richard, 36, was filming a show about tidal bores, waves which travel up a river channel from the sea.

But his show was anything but boring, after one huge wave appeared out of nowhere to give the nature guru a scare.

The well-known Brazilian TV presenter can be seen making a splash as he explains the natural phenomenon with the cameras rolling, posing in front of a choppy river as he speaks.

As he stands in front of the raging river, an ominous surge of muddy water sprays up in front of him, before being followed by an enormous bore.

Richard doesn’t even have time to wave for the camera as the river breaks its banks and sends a brown tidal wave in his direction.

With a stick still in his hand, Richard frantically sprints away from the wave, eventually running off camera to the dramatic action-movie soundtrack.

Moments later, the cameraman is forced to leg it as well, with the bore showing no signs of stopping.

Adrenaline pumping, the shouty nature presenter eventually returns to the river bank when the wave finally washes back.

The strange video finishes with Richard shouting to himself and holding his stick aloft as he traipses back towards the river.

The clip was uploaded to LiveLeak, where commenters delighted in the strange footage.

One viewer said: “Does he think that he's Moses or something?”

Another chipped in: “Next week, Richard will explain how volcanoes work while standing on the rim of an erupting volcano.”

Tidal bores are especially remarkable natural phenomena because the waves they create go against the natural flow of the river.

The Severn River in England is well known for its bores, which have been known to reach speeds of 13 miles per hour and heights of over 9 feet.
