Josh has got his skis and he's ready to go...
Here he is at the top of the exhibition slope at the Metro Ski & Snowboard show in London. Riders go down the slope - then do tricks on the half-pipe.
It's a long way down, but Josh has no fear. He's been entering free skiing competitions for years!
He's off! Free skiing involves tricks and jumps, but loads of other stuff - like going down the slope backwards and skiing off the main runs of a mountain.
Josh has been skiing since he was six. He thinks people should give it a go. "You either like it, or you don't," he says.
