I am linking to an article I think a lot of people should read, called Are You Disciplined Enough To Race Less, by Jay Johnson. It may sound familiar, since I've touched on this before. If you don't read his blog already, I strongly recommend you do. Between the strength routines and workout videos to the candid discussion on what it takes to be a better runner, his blog is one resource I frequent for advice for myself and for the runners I work with.
So take a read through and let me know what you think
