...But Matt Johnson may want to try it a few more times before competition begins!
A few spectators watch the action, but thousands of fans will line the track on Friday and Saturday night.
He'll be hoping to sweep all before him in the finals, but first Cameron Naasz wanted to sweep the ice.
Time to focus and get ready for his first run down the track.
And away he goes! Naasz speeds off for his first taste of the tough obstacles ahead.
The prize awaits, but who will be holding it on Saturday night?
