Mac and guide Jack Leitch won the World Cup overall title at the end of the 2014 season. World champion Para-Alpine skier Mac Marcoux and his guide Jack Leitch credit their relationship for most of their success. Every time Mac switches a guide, there are new things to learn in the relationship, but that has not slowed him down. Mac has since earned 7 discipline globes so far in his career, and continues to be a regular podium threat in all disciplines on the World Cup circuit.
