Dr. George Sheehan was medical columnist for Runner's World for several years and was an active runner and writer about running. One of his essays was called"The Basics of Jogging: How Fast, How Far, How Often?" . That essay was the first article I read in the running literature, and I received it at the first meeting of the Digital Running Club in Maynard, Massachusetts in 1976. The essay was pure common sense , and I've followed his advice for over 33 years and have enjoyed running with only one injury. I'll be eternally grateful to " D oc" Sheehan for his guidance.
As a tribute to George Sheehan, I've posted that essay in this site for all to read and enjoy (additional essays by "Doc" Sheehan are at georgesheehan.com ).
