A 1:30 half marathon requires about 4:16/km or 6:52/mile. A 1:45 requires 4:59/km or 8:01/mile, a 2:00 requires 5:41/km or 9:09/mile, and a 2:30 requires 7:07/km or 11:27/mile. For an exact target between the rows, use our Running Pace Calculator.
Half marathon pace chart: finish time, pace per km and pace per mile
This complete half marathon pace chart converts finish times from 1:00 to 4:00 into pace per kilometer, pace per mile and the even 10K checkpoint. The calculations use the full 21.0975 km race distance. Individual splits can still vary with hills, wind, temperature, turns and pacing strategy.

Paces are calculated from 21.0975 km and approximately 13.1094 miles, then rounded to the nearest displayed second. The 10K column assumes an even average speed.
Use the Running Pace Calculator instead of rounding your goal to the nearest five-minute row.
Common half marathon goal paces
Sub-1:30 pace
Exactly 1:30:00 is about 4:16/km or 6:52/mile. To break 90 minutes, average slightly faster than the rounded display pace.
Sub-1:45 pace
Exactly 1:45:00 is about 4:59/km or 8:01/mile, with an even 10K checkpoint near 49:46.
Sub-2:00 pace
Exactly two hours is about 5:41/km or 9:09/mile. The even 10K checkpoint is roughly 56:53.
Sub-2:30 pace
Exactly 2:30:00 is about 7:07/km or 11:27/mile, with an even 10K checkpoint around 1:11:06.
If one of these is your next target, use our 12-week half marathon training plan to turn the goal pace into a structured training progression.

An exact 8:00/mile average gives about 1:44:53. A 9:00/mile average gives about 1:57:59, and a 10:00/mile average gives about 2:11:06.
How to calculate half marathon pace
Pace formulas
Pace per kilometer: finish time ÷ 21.0975
Pace per mile: finish time ÷ 13.1093787
Average speed in km/h: 21.0975 ÷ finish time in hours
For example, a 1:52:30 target is 6,750 seconds. Divide that by 21.0975 and you get about 320 seconds per kilometer, or approximately 5:20/km.
How to choose a realistic half marathon pace
A pace chart handles the arithmetic, but the goal still needs to match your current endurance. A recent 10K can help estimate the direction of your target, while long-run consistency and race-specific sessions show whether you can carry that fitness for 21.1 km.
Anchor the goal to recent long runs and start the first 5K under control.
Compare with the 10K pace chart, then validate the slower half-marathon pace in training.
Race-specific blocks and threshold work should make the target familiar without requiring a full race simulation.
Use pace together with effort instead of forcing identical splits in difficult conditions.
What research says about half marathon pacing
More even pacing is associated with stronger performance groups
An analysis of 7,258 half-marathon finishers from Ljubljana found a gradual decline in speed across the race on average, with half-marathon pacing more even than marathon pacing. Another analysis across performance levels found less pace variability among better-performing half-marathon runners.
That does not mean every kilometer should be identical. Course profile, wind and temperature can change the appropriate split even when the overall effort is well controlled.
Use the chart as an average target. Avoid turning the opening kilometers into a separate, faster race that you must repay later.
0–5K: establish control
Settle near target effort and resist the urge to bank time.
5–15K: protect the rhythm
Use lap pace and cumulative checkpoints while letting terrain move individual splits.
15–20K: defend the pace
If form remains stable, maintain the target instead of waiting for the finish to re-engage.
Final 1.1K: race what remains
Increase effort progressively if you still have capacity.
Half marathon pace is not your pace for every run
Easy running
Easy days support aerobic development and recovery. See our easy run pace guide and Zone 2 running guide.
Tempo and threshold
Use tempo running and lactate threshold training to build sustainable aerobic speed.
Intervals
Intervals can be faster than race pace without becoming your default training speed. See our interval training guide.
Race-specific work
The 12-week plan shows how goal-pace work can fit around easier running and long runs.
For more context on performance, see our guides to VO2 max and running economy.
Fueling and pacing over 21.1 km
Fuel and hydration become more relevant as race duration increases. Practice your race products in training instead of introducing a new strategy on race morning, and adjust pace and fluid planning to conditions. Our Endurance Carb Intake Calculator can provide a practical starting point for carbohydrate planning.
Running wide around turns, weaving through runners and normal GPS error can add recorded distance. Use official course markers and cumulative race time alongside GPS pace.
Half marathon pace after swimming and cycling
A half marathon is also the run leg of a 70.3-distance triathlon, but an open half-marathon pace should not automatically be copied after a swim and 90 km bike. Bike intensity, fueling, heat and durability change what is sustainable. See our half-distance triathlon guide and cycling for triathlon guide.

How this half marathon pace chart was calculated
These are mathematical conversions rather than population averages.
Exact distance
We use 21.0975 km and 1 mile = 1.609344 km.
Consistent rounding
Pace and checkpoint displays are rounded to the nearest second.
Even-pace reference
Checkpoint splits assume one average speed and are reference points, not a rule for every segment.
