A Canadian kayaking daredevil is making waves online after he shared a video of himself manoeuvring down a drained aqueduct at breakneck speed.
Vancouver-based Ben Marr rode the Lions Bay Slide into Howe Sound in British Columbia at speeds of up to 56km/h, capturing the whole experience on camera.
The footage, filmed from three different angles, shows Mr Marr push off an embankment in his whitewater craft.
Armed with only a paddle, the extreme sportsman quickly builds speed and his kayak can be heard dragging on the concrete as he snakes down the slide.
A camera fixed to his helmet ensures viewers have a front seat view of the action as he hits the water.
The video went viral after being posted on Facebook on September 30, tallying more than 1110 likes and 1950 shares by Friday.
