I pace many half marathon and marathon races. Usually what I need for that is: instantaneous pace, average pace, and lap distance.

I tend to plan my pacing for equal effort, so each lap pace is adjusted for elevation such that in the end the overall pace is just slightly faster than what is needed for goal pace.

Needless to say, I use my Garmin Forerunner 945 for this.

If anyone is running the Seattle Marathon, I'll be there pacing :)
