I have been reading about Canova recently and I have noticed that he seems to focus on goal pace training. In theory, it seems like a good idea to try to extend the length of time that you can run at your goal pace for a certain race distance, but then I was listening to a podcast with Tom Schwartz and I was reminded about how much he dislikes goal pace training. I think Tom definitely presents a better argument, he is able to explain the physiology of training at goal pace vs. current fitness level.
What does everyone else think? Goal pace training or current fitness training?
