Benji Durden (born August 28, 1951) is a Boulder, Colorado based coach of elite runners who came to prominence as a distance runner in the early 1980s, at the height of the American running boom.
Durden was a member of the titular 1980 Summer Olympics United States marathon team, placing second against what to that point was perhaps the deepest field of American marathoners ever assembled.
With a personal record of 2:09:58, Durden recorded 25 sub-2:20 marathons in less than a decade.
He ranked among the top ten US marathoners six straight years, reaching seventh in the world in 1982.
