What Are Splits in Running?


Updated April 29, 2014

Definition: The time that it takes to complete a specific distance in running. For example, if you're running 5 miles, your time at each mile marker is called a "mile split". Some runners use splits to see if they're pacing evenly. So, if you're running a timed mile, you may check your splits every 1/4 mile to see if you're on pace.
