Mark Robert Conover (born May 28, 1960 in Contra Costa County, California) is an American long distance runner and coach. He is most famous for his unexpected strategic victory at the 1988 United States Olympic Trials marathon, qualifying him for the 1988 Summer Olympics in Seoul, South Korea, where he was a member of the U.S. Team. The winning 2:12:26 at the Olympic trials was his personal best.
Conover showed his potential running for Miramonte High School in Orinda, California, finishing 5th at the CIF California State Meet in the 2 mile behind Jeff Nelson just a year before Nelson would set the record in the event that would last almost 30 years.
His time as a professional runner was cut short in 1993 by a two-year battle with Hodgkin’s disease. Professional internships that developed into planning jobs in San Luis Obispo County had him training in the area. He began as an assistant coach at Cal Poly, San Luis Obispo. In 2009 he was named director of track and field and cross country for the university. Conover led his teams to Big West Conference women's titles in 2012, 2013 and men's titles in 2009, 2011, 2012, 2013
