Great Articles for the Marathon Runner

I ran across a new resource for Marathon and general running advice.  It is the archive of articles at Running network.  Rather than just a compilation of their own articles, they have hand selected articles that appear to be quite strong.  They come from a wide array of sources.

The first article I read was on progression running from Run Washington.

Run long, run hard, get fast.
