I know it’s a blog and not an essay. I know it’s informal; however, shouldn’t the writing at least be edited for clarity? Mr. Valle, what do you mean when you write “young coaches with great education and knowledge fail to prescribe the wrong speeds in training to correct technique.” Coaches fail to prescribe the wrong speeds? Should coaches succeed in prescribing the wrong speeds? This is a great site, and I have found valuable information here. I look forward to this blog; Mr. Valle is clearly a knowledgeable track authority. In this case I simply wish a little care had been taken to clean up some of the writing. I don’t mind simple grammar errors–the usage of “their is less information” when “there” is correct or writing “looses control” when “loses” is meant–but errors that cloud meaning should be addressed. Fragments such as “With the lats involvement with sprinting” simply don’t add much to the topic.
