Editor's note: Hi, this is Gus. I recently found this article by Jim Gourley on Active.com about using power for running. I thought it was interesting, ahead of its time, and relevant to our mission to enable runners to train using power. I had a chance to speak with Jim. He had a lot of comments, and agreed to let us reproduce his article on our blog. I hope that you find this article as interesting as I did.
Power meters have become a mainstream training tool for cyclists over the past several years. Meanwhile, runners continue to rely on heart rate monitors as the only way to monitor training zones and effort. But this could soon be changing.
