Joe Pete Wilson (born May 22, 1935) skied for the US in cross-country at the 1960 Winter Olympics, but later became a well-known administrator in the United States.  Wilson also wrote several books on cross-country skiing, all co-authored by William J. Lederer.  Wilson set up the cross-country ski area at the Trapp Family Lodge in Stowe, Vermont - the lodge established by the Trapp family of "Sound of Music" fame.  In 1973, Wilson organized a meeting of 25 ski areas and established the National Ski Touring Operators' Association.  Wilson was named as its first President from 1973-1977.  After several name changes it is now called the Cross Country Ski Areas Association (CCSAA).  CCSAA is an international association of US and Canadian cross-country ski areas.  Joe Pete is also known for setting up an inn in Keene, New York, the Bark Eater Inn, and developing the ski trails around the inn. The sport of cross-country skiing encompasses a variety of formats for cross-country skiing races over courses of varying lengths according to rules sanctioned by the International Ski Federation and by various national organizations, such as the U.S. Ski and Snowboard Association (USSA) and Cross Country Ski Canada.  International competitions include the FIS Nordic World Ski Championships, the FIS Cross-Country World Cup, and at the Winter Olympic Games.  Such races occur over homologated, groomed courses designed to support classic (in-track) and freestyle events, where the skiers may employ skate skiing.  It also encompasses cross-country ski marathon events, sanctioned by the Worldloppet Ski Federation, and cross-country ski orienteering events, sanctioned by the International Orienteering Federation.  Related forms of competition are biathlon, where competitors race on cross-country skis and stop to shoot at targets with rifles, and paralympic cross-country skiing that allows athletes with disabilities to compete at cross-country skiing with adaptive equipment. Odd-Willy Martinsen (born 20 December 1942) is a retired Norwegian cross-country skier who competed during the 1960s and 1970s.

At the 1969 Holmenkollen ski festival, he won the 15 km race.  For his cross-country skiing successes in Norway and abroad, Martinsen received the Holmenkollen medal in 1969.  Thirty-two years later, his daughter, Bente Skari, received the Holmenkollen medal, making them the only father-daughter combination to ever win the prestigious honor.
