David Lyon was born in Winnipeg. As an athlete at Oklahoma Baptist University, Lyon was the two-mile champion in the Oklahoma Athletic Conference and placed fourth at the United States National Championships in 1961.
Lyon became a coach after injuries forced him to retire from competition. In 1966, he founded the Razorbacks Track Club and was the Meet Director for the provincial high school track and field championship from 1966 to 1969. Lyon also served as the events chairman for track and field at the Pan American Games in Winnipeg.
In the 1970’s, Lyon alternated duties as a coach and manager. He led Canadian teams in dual meets against the United States and the Soviet Union, served as a meet director for national and provincial track competitions, and managed national training camps in 1974 and 1975. Since his first appointment as manager of the Canadian team at the World Cup trials in Mexico in 1977, Lyon has led teams to Scotland, Puerto Rico, New Zealand, Romania, Venezuela, Japan, Rome, the United States, Korea, and Cuba. At the 1988 Olympic Games in Seoul, South Korea, Lyon was the official who notified the coach of Ben Johnson that the sprinter had tested positive for steroid use and would lose the Gold Medal in the 100 metre event.
Lyon has served as the national team manager on many occasions since 1984 and has led the Canadian contingent to the Pan American Games in Havana, Cuba. From 1977 to 1988, he was the Director for the Legion Athletic Camp at the International Peace Gardens and was the head coach and administrator for seven years. In 1981, Dave Lyon was also honoured as the Volunteer of the Decade for Track and Field. He has also served as Director of Athletics with Sport Manitoba.
