You can read more about the preamble to all of this and the motivations behind why and how I went about compiling this collection on my blog:
But I'll spare you those details here. The bottom line is that I've compiled a somewhat-organized 291-page .pdf of John Kellogg's writings. The collection contains Kellogg's posts here on LetsRun, from about 2003 to recently, his articles for the front-page "JK Speaks" series, the contents of his short-lived website ParagonRunning.com, which was a partnership between John Kellogg and 1980 Olympic Trials Marathon 3rd-place finisher Kyle Heffner, and the "original" Training Wisdom of John Kellogg, a short compilation of posts created by Tim Galebach (carolinarunner) in 2003.
I hope you enjoy reading through this collection and that you find it a helpful resource in becoming a better “student of the sport.”
