Track Split Time Calculator

Work out track split time instantly with clear inputs, formula shown and shareable results.

About Track Split Time Calculator

The even lap split is the target time divided by the number of laps, and average speed is race distance over race time in metres per second. Track racing is won on pace discipline, and a four minute mile is simply four consecutive 60 second laps, which is far easier to execute than to feel.

Formulas

Lap split

lap split = target time / (race distance / lap length)

Average speed

speed = distance / time

Worked example

With the default values below, Track Split Time Calculator returns Target lap split of 60.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Track Split Time figure worked out?
