Question about the extreme sports related expression I'm reading about Winter X games and since I am not very aware of these kind of extreme sports, I don't understand what Bertoni managed to do from the second try? Could somebody explain? Here's the phrase: With the height of the Superpipe increased a start list was expected to lay down some huge tricks and they didn’t disappoint…upsetting the form book on the second of his three runs was French rider Bertoni. Thanks for your help.
