What is "nastar"

NASTAR (an acronym for NAtional STAndard Race) is the world's largest known recreational ski and snowboard race program. It allows ski or snowboard racers of all ages and abilities, through a handicap system, a way to compare themselves with one another and with the national champion, regardless of when and where they race. Since the program's beginning in 1968, more than 6 million NASTAR racer days have been recorded. It has been available at more than 100 ski resorts in North America and 1 in Australia. Many U.S. Ski Team stars got their start ski racing in NASTAR programs.
