How is pace different from speed?

Pace expresses how long it takes to cover a fixed distance (like minutes per kilometer), while speed expresses how much distance is covered in a fixed time (like kilometers per hour) — they are inverses of each other.

What is a good running pace?

A "good" pace depends entirely on your fitness level and goals — recreational runners often fall somewhere between 5:00 and 7:30 per kilometer, but any consistent pace that suits your training goal is a good one.

Can I use this for cycling or swimming?

Yes for cycling, since it uses the same distance-and-time math. Swimming pace is usually measured per 100 m rather than per km or mile, so you may need to adjust the distance entered accordingly.

How it works

The calculator divides your total time by the distance covered to find your pace, and separately converts the same distance and time into a speed in kilometers and miles per hour.

Formula & methodology

Time is converted to seconds and distance to kilometres and miles (1 mile = 1.609344 km). Pace is time per unit of distance, and speed is distance per hour, so both units are shown.

PacePace = Total time ÷ Distance

SpeedSpeed = Distance ÷ (Total time in hours)

ConversionMiles = Kilometres ÷ 1.609344

What each term means

Total time: Hours, minutes and seconds combined.
Pace: Shown as minutes:seconds per km and per mile.

Worked example

Running 5 km in 25 minutes gives a pace of 5:00 per km (about 8:03 per mile) and a speed of roughly 12 km/h (7.5 mph).

Common uses

—Planning a target pace for an upcoming 5K, 10K, half marathon, or marathon.
—Converting a finish-time goal into the per-kilometer or per-mile splits needed to hit it.
—Comparing training run paces against race-day pace goals.

Important notes

—Enter distance in either kilometers or miles — the calculator converts and shows results in both units.
—This works for any steady-pace activity, not just running — walking and cycling splits can be calculated the same way.
