Quick Answer

Pace (min/km) = Total time in minutes ÷ Distance in km. Example: 55 minutes for 10km = 5:30 min/km. To convert pace to speed: Speed (km/h) = 60 ÷ Pace (min/km). At 5:30/km your speed is 10.9 km/h.

What Your Pace Actually Means for Training

Knowing your race pace is only half the picture. The more important number for day-to-day training is your easy pace — the pace you should run for the majority of your sessions. Most runners make the mistake of running too fast on easy days, which accumulates fatigue without building fitness proportionally.

A well-established training principle is that roughly 80% of weekly volume should be at easy effort — conversational pace, where you can speak full sentences without gasping. The remaining 20% is where harder sessions like tempo runs, intervals, and race-pace work belong. For more on how pace connects to running form and efficiency, see our guide on best running form for long distance.

Training Zone Effort Pace vs 5K Race Pace Purpose % of Weekly Volume
Easy / Recovery Conversational — can sing 60–90 sec/km slower Aerobic base, recovery, long runs ~70–80%
Steady / Aerobic Comfortable but purposeful 30–60 sec/km slower Aerobic development, medium-long runs ~10–15%
Tempo / Threshold Comfortably hard — short phrases only 15–25 sec/km slower Lactate threshold, race fitness ~5–10%
Interval / VO2max Hard — can't speak At or faster than 5K pace Speed, VO2max, race-specific fitness ~5%

To use this table: find your current 5K pace from the charts above, then calculate each training zone by adding or subtracting the stated seconds per km. For example, if your 5K pace is 5:30/km, your easy pace is roughly 6:30–7:00/km and your tempo pace is around 5:45–5:55/km.

How to Find Your Pace for a Target Race Time

If you have a goal finish time for a race, work backwards to find the pace you need to maintain. The formula is:

Required pace (min/km) = Target time in minutes ÷ Race distance in km

Examples: A 2-hour half marathon requires 2:00:00 ÷ 21.1km = 5:41/km. A sub-45-minute 10K requires 45:00 ÷ 10km = 4:30/km. A 4-hour marathon requires 240:00 ÷ 42.2km = 5:41/km.

Once you know your target pace, use the training zones table above to set your easy pace for long runs and recovery days. Running every session at race pace is one of the fastest routes to burnout or injury — the easy pace work is what builds the engine that sustains race pace on the day.

For specific race pace breakdowns and training plans built around target times, see our guides to the 1:45 half marathon pace and the 16-week half marathon training plan.

Pace Per Km vs Pace Per Mile: Conversion Table

Australian races are measured in kilometres, but many international training resources use miles. Use this table to convert between the two.

How to Improve Your Running Pace

Pace improvement is a byproduct of consistent training, not something you chase directly in every session. The most effective approaches for runners at all levels are:

Run more easy kilometres. The single biggest driver of pace improvement for most recreational runners is increasing their weekly volume at easy effort. More aerobic kilometres means a stronger engine — your heart pumps more blood per beat, your muscles use oxygen more efficiently, and your body learns to burn fat more effectively at higher intensities. If you are running three times per week, adding a fourth easy session will improve your race pace faster than making three harder sessions harder.

Add one quality session per week. Once you have a consistent base, adding a weekly tempo run (20–40 minutes at threshold pace) or interval session (6–10 × 400m at 5K effort) introduces the speed stimulus that translates easy-run fitness into faster race times. More than two hard sessions per week is counterproductive for most recreational runners.

Improve your running cadence. Running with a higher cadence (steps per minute) reduces ground contact time, lowers injury risk, and often leads to a naturally faster pace at the same effort. Most recreational runners benefit from targeting 170–180 steps per minute. Our guide to running cadence explains how to measure and gradually increase yours.

Check your easy pace is actually easy. If your “easy” runs leave you tired, your easy pace is too fast. A useful test: you should be able to carry on a full conversation — not just gasp one-word answers — for the entire easy run. Slowing down on easy days often leads to faster race times because accumulated fatigue clears and quality sessions can be run at genuine quality effort. See our detailed guide on how to calculate pace for running for more on pacing by effort.

Want a Training Plan Built Around Your Target Pace?

Knowing your pace is step one. A structured training plan built around your current fitness and race goal is step two. Our running coaching programs include personalised pace targets for every session — easy runs, tempo work, and race-day strategy — so you always know exactly how fast to run.

FAQ: Running Pace Calculator

How do I calculate my running pace per kilometre?
Divide your total run time (in minutes) by the distance in kilometres. For example: 55 minutes for 10km = 5:30/km.

What is a good running pace per km for beginners?
7:00–9:00 min/km is a good beginner easy pace — slow enough to hold a full conversation. Your pace will naturally improve over 8–12 weeks of consistent training without trying to force it.

What is the difference between pace and speed?
Pace is time per distance (min/km). Speed is distance per time (km/h). At 6:00/km your speed is 10.0 km/h. Most runners use pace because it maps directly to race splits.

How do I convert pace per km to pace per mile?
Multiply by 1.609. At 5:00/km your mile pace is 8:03/mile. Use the conversion table above for common paces.

What training pace should I run at?
About 80% of your running should be at easy pace — 60–90 seconds per km slower than your 5K race pace. The remaining 20% is tempo and interval work. Running easy days too fast is the most common training mistake.
