Running pace measures the time it takes to cover a set distance, usually expressed in minutes per kilometer or minutes per mile. It is the most common metric runners use to plan workouts, set race goals, and track improvement over time. Unlike speed (distance per time), pace tells you directly how long a run will take.

Pacing Your Races

Knowing your pace helps you start races at the right effort level, avoid going out too fast, and execute a smart race strategy. Many GPS watches and running apps display real-time pace so you can make adjustments on the fly.

How to Use Pace for Training

Different training sessions call for different paces. Easy runs should feel conversational (typically 1-2 minutes slower than race pace). Tempo runs target your lactate threshold pace, which is roughly the pace you could sustain for about an hour. Interval workouts use paces faster than race pace to develop speed and VO2 max.

Negative Splits Strategy

Negative splitting means running the second half of a race faster than the first. This approach conserves glycogen stores early on and reduces the risk of hitting the wall. To practice, start your long runs 10-15 seconds per km slower than goal pace and gradually increase to goal pace or faster in the final third of the run.
