[01]What Is a Split in Track?

Splits, explained

Splits within a race

In a longer race, a split is your cumulative or per-lap time at a checkpoint, like your 200 split in a 400 or your mile split in a two-mile. They show whether your pace is even or fading.

Why splits matter for pacing

Even, well-judged splits usually beat a fast start and a fade. Comparing your splits to a goal pace tells you exactly where a race went right or wrong.

Relay splits

In a relay, your split is the time for your leg. Because legs two through four start moving as the baton arrives, relay splits run faster than an open race from a standing start.

What Is a Split in Track? FAQ

Common questions athletes and coaches ask about this topic.

What is a split in track?
Your time at a checkpoint within a race, or the time for one leg of a relay. Splits break a race into pieces to study pacing.
What is a good split for pacing?
Even splits, where each segment is close to the same pace, usually beat going out fast and fading. Compare your splits to your goal pace.
Why are relay splits faster than open times?
Legs two through four start moving as the baton arrives, so the flying start makes a relay split faster than a standing-start open race.
