Training Note: paces

Based on an article I was reading, here's a set of my estimated running paces:

Endurance = 8 minutes, 7.5 mph
Stamina = 7:30, 8 mph
Speed = 7:00, 8.57 mph
Race = 6:30, 9.23 mph
Sprint = 5:45, 10.43 mph

The article had only 4 paces: I added race because it seems I function differently in competition.
For my *target* paces, to get some effective training done this year, I want to up them all by about 15 seconds and run in those brackets over all distances, from one mile to 5K and on up to 18 miles.

Here are the target paces then:

Endurance = 7:45 minutes, 7.75 mph
Stamina = 7:15, 8.28 mph
Speed = 6:45, 8.9 mph
Race = 6:20, 9.47 mph
Sprint = 5:40, 10.6 mph

From here on all runs logged should have one of these paces as a goal (though running on trails gives a bit of a variation, maybe 15-20% slower?). Make it so.
