This looks like nice little calculator...
http://www.mcmillanrunning.com/index.php/calcUsage/calculate
It tells you how fast you could run any distance between 1 kilometer - 100 miles (under 1 km times are more like educated guesses) based on your current record time on some distance. It also gives you speeds to use in different type of training runs. As I don't like using heartrate monitor or following any running program or schedule(I like to decide by myself how much I run), this calculator looks like fine tool to use on some of the runs.
For example, I have always thought that intervals should be run on full speed, and calculator says that I should run 400m intervals with 10-20 seconds slower pace than my maximum 1k pace is. Now, that makes intervals actually a lot more comfortable and motivating exercises. More like relaxed dashes with appropriate effort instead of hard effort. Latter has it's own kind of joys, but it's very unmotivating to begin with full effort exercise.. So I have not done intervals for a long time. While I have on some level known that I could run intervals slower than maximum speed, it's better have some given values what speeds are relevant to use, otherwise it seems that I slip from that chosen speed and go try making a record times..
