Pace Calculator

Multipoint Pace Calculator

Record the distance and the clock time at a few points, and this works out the pace of each leg between them as well as your average to that point. Distances and times are from the start, as a watch shows them at a marker.

Finish Time Calculator

Part way through a race, this estimates your finish time from the distance you have covered and the time on the clock, at the pace you have held so far.

How to use this calculator

1. Choose which of Pace, Time or Distance you want worked out. That box locks, because it is the answer rather than a question.
2. Fill in the other two. Distance and pace each carry their own unit, so a 10 km run can be paced per mile.
3. Press Calculate. The answer appears in the panel and is written back into its own box, so you can switch target and carry it into the next sum.

Two more tools sit above. The Multipoint Pace Calculator takes the distance and clock time at several points and works out what each leg cost you as well as your average to that point — the difference between "I ran a 25-minute 5K" and "I went out too fast". The Finish Time Calculator answers the question you ask yourself mid-race: at this pace, what will the clock say at the line, and how much is left?

Pace versus speed

Pace is how long it takes to cover one unit of distance — minutes per kilometre or per mile — and it is how most runners think about effort. Speed is the inverse: distance covered per hour. A pace of 5:00 per kilometre and a speed of 12 km/h describe exactly the same run, just from opposite directions.

The formula

Pace and speed come straight from distance and time:

• Pace = time ÷ distance (e.g. seconds per kilometre)
• Speed = distance ÷ time (e.g. kilometres per hour)

The equivalent finish times apply your pace evenly across each race distance, so they show what you would run if you held the same pace throughout.

A worked example

Run 5 km in 25 minutes and your pace is 1,500 seconds ÷ 5 = 300 seconds, or 5:00 per kilometre (about 8:03 per mile). Your speed is 12 km/h (about 7.46 mph). Held evenly, that pace projects to:

Distance	Equivalent time at 5:00 /km
5K	25:00
10K	50:00
Half marathon	1:45:29
Marathon	3:30:58

What counts as a good pace

There is no universal benchmark — pace depends on distance, terrain and experience. Beginners often run 7–8 min/km (11–13 min/mile), while seasoned recreational runners hold 5–6 min/km (8–10 min/mile) over a 5K. Rather than compare with others, watch your own pace drift downward as fitness builds; that trend is the real measure of progress.

Pacing yourself well

The most common racing mistake is starting too fast. Aim to run the first half slightly conservative and finish as strong as or stronger than you started — a "negative split." Even effort, not a fast start, almost always produces your best finish time.

Using pace in training

Knowing your pace keeps easy days genuinely easy and hard efforts controlled. Because the equivalent times assume you hold one pace for the whole distance, treat a marathon time projected from a 5K as optimistic — real races slow over distance as fatigue sets in. Pair pace with the target heart rate calculator to judge intensity from two angles. This is general information, not coaching or medical advice.
