Speed. Whether you are an elite athlete or a weekend warrior, the road running world seemingly revolves around how fast you can run. Tell someone you ran a marathon, they'll ask you how long it took. Sign on to any running forum, and people will be discussing PR's (personal records) mile splits, tempo runs, you get the idea. Speed seems to matter, a whole lot. But the truth is, runners often get burnt out on the excessive focus on speed and time.
