What is a negative split?

A negative split means running the second half of a race faster than the first half. This calculator takes your race distance, goal time, and chosen split percentage to produce target paces for each half of the run.

How do I use the negative split calculator?

Enter your race distance and goal finish time, then set how much faster you want the second half to be. The calculator returns a slightly slower first-half pace and a faster second-half pace that together hit your goal time.

Why race with a negative split?

Starting conservatively conserves glycogen and limits early fatigue, so you can finish strong and often run a faster overall time. Many distance records and personal bests are set with a negative split rather than fading in the final miles.
