How many laps is a 1500m race?

A 1500m race on a standard 400m track is 3.75 laps. Runners start on a staggered mark 300m before the finish line, so they run 300m to complete the first partial lap, then 3 full laps.

Should I run even laps or negative split?

For most track races, even laps are the most efficient strategy. A slight negative split (faster second half) is ideal for experienced racers. Avoid going out too fast in the first lap, which is the most common mistake.

How do I time my laps during a race?

Use the trackside clock visible from the home straight, or a GPS watch with lap button. Many athletes have a coach calling split times from the infield. Press the lap button each time you cross the start/finish line.

What are standard track race distances?

Standard outdoor track distances: 800m (2 laps), 1500m (3.75 laps), 3000m (7.5 laps), 5000m (12.5 laps), 10000m (25 laps). Indoor tracks are typically 200m, so double the lap count.

How We Calculate This

Lap Time Calculation

The calculator divides the goal time evenly across the required number of laps:

Total Laps = Race Distance / Track Length

Time per Lap = Goal Time / Total Laps

Cumulative split times show your expected time at each lap mark. For distances that do not start on the finish line (e.g., 1500m on a 400m track), the first split covers the partial opening lap.
