Hundreds of downhill daredevils took to the hills of Calgary last week for the 11th World Downhill Skateboarding Championships.

More than 220 racers from all over the world took part in the high-speed, high-stakes races in the Olympic Park, home of the 1988 Winter Olympics.

Downhill Skateboarders stand upright on longboards and can reach speeds of up to 55mph.

James Kelly, 22, from Los Angeles won the men's race.

He said: "I am honoured, I am stoked, I've been racing since 2007, so it's been a dream to win the World Championship. I am well stoked it's under my belt now and now I am hoping for the series".
