Training for Stage Racing

On the eve of Joe Martin, I found this article on the physiological demands of stage racing to be pertinent and interesting.  I had to read it a couple of times in order for it to really make sense to me,  but there is some good information in here (even if you don't plan on participating in a stage race).  I like how they take the analysis of the different types of racing and then mention using this information to create training that simulates these demands.  This is known as "specificity" and I think we could all benefit from doing more of this in our training.
