He went to the University of Colorado in Boulder, where he met and was coached by Bob Beattie. A three-time letterman, Heuga won the 1963 NCAA championship in the slalom. With Beattie also leading the U.S. Ski Team, Heuga, along with fellow Buffaloes Buddy Werner and Bill Marolt (and future CU alumnus Billy Kidd), formed the squad's nucleus for the 1964 Winter Olympics. Both Kidd and Heuga became the first American men to win Olympic medals in Alpine skiing, respectively capturing silver and bronze in the slalom.
