Speed

I know that I follow this advice, without even thinking of it. If you look at my mile splits on the Daily Mile widget at the bottom right, you'll see my last miles tend to be faster than the middle miles. Weirdly, the people in my pace group seem to follow this advice, too. We all speed up the last mile or two, even though we're not running slower than pace up to that point and don't discuss trying to finish early.
