Before you can train at your target pace you must, of course, choose a target pace, which means you must choose a goal time for your event.
A target pace is an average running pace associated with an event time goal. If your event goal is to run a 3:45 marathon, your target pace is 8:35 per mile. If your goal is to run a 39:59 10K, your target pace is 6:26 per mile. And so forth.
Whenever you have an event time goal, your entire training program should be focused toward achieving the ability to sustain your target pace in that event. This doesn't mean you should always run at your target pace, of course. But it does mean you should include some target-pace running in your weekly training throughout your training program and do a fairly large amount of training at or near your target pace in the final weeks before your event.
