Even pacing. If I've got a definite time target I might start off a bit quick for the first mile or two, build up a very modest cushion in the first half, not more than half a minute or so, then aim for metronomic splits for as long as possible. Throw the kitchen sink at it in the last mile when you know the wheels aren't gonna fall off. (Hopefully.)
