Combining the sports of cross-country skiing with precision target shooting, the biathlon has evolved from an ancient hunting method to military ski patrols, to an Olympic and World Cup sport. It requires strength, endurance, solid skating skills and a high degree of shooting accuracy. Add cold and changing snow conditions to the mix and you have one of the toughest physical and mental challenges a competitor can face. The Ethan Allen Firing Range in Jericho is home to one of the premiere biathlon training facilities in North America and is managed by the National Guard. The Guard has produced a number of world-class biathletes. The Ethan Allen facility attracts competitors from all over the world. Host Marianne Eaton joins Guard member and Olympic biathlon racer Dan Westover on the range in Jericho for an introductory lesson to the sport of biathlon.
