Great Britain snowboarder Billy Morgan has admitted that the slopestyle course in Sochi scared him during training.
Several athletes have voiced their concerns about the course as Norway's Torstein Horgmo has been ruled out of the 2014 Winter Olympics after breaking his collarbone, while the USA's Shaun White has pulled out of the event.
"It's been a bit scary getting used to hitting the jumps," he told BBC Sport. "The jumps weren't raked properly, which hopefully they can sort tomorrow so they are smoother and not as intense to land."
Morgan will be competing in his first Games, after finishing fourth in the World Championships last year.
