Comments

Easy pace running is conversational running. Ideal for Tuesday nights
Steady running is comfortably fast. A Tuesday night, but pushing it a little.
Threshold pace is 3-4 word answer pace. A training pace often used on Thursday night training
V02 Max pace is a hard pace where it is hard to talk. Another pace often used on Thursday night training

These times are just rough estimates. They assume that you have done all the necessary training to achieve the desired distance. The mile pace is just a ballpark figure as you can't really figure out middle distance pace from your endurance pace.
