 "A" and "B" are for slower and inexperienced riders and run parallel to each other.Lane "C" is for solo, more experienced riders, and follows a significantly different alignment from the other two lanes, with a different arrangement of turns, including the presence of a triple-down drop and one more steep straightaway drop.The Alpine slide has mostly been unchanged since construction, the only alteration being a redesign of the lower section of the layout for both tracks as part of One Ski Hill Place construction in 2009.
