Cumulative clock time at each mile marker, at perfectly even pace over 21.0975 km. Nobody runs even splits and nobody should try to; use these as the line you are measuring drift against, not as an instruction. The difference between the number here and the number on your watch is information — a minute up at 15 km is a race you are about to lose.

The pace, and the arithmetic

A 1:30 half marathon is 6:52 per mile, or 4:16 per kilometre, held for 13.1 miles (21.0975 km). On even pace you pass 10 km at 42:40 and 10 miles at 1:08:39. To finish under 1:30, run 6:51 per mile, which finishes in 1:29:48.

How the numbers are worked out

1:30:00 is 5,400 seconds.
Per mile: 5,400 ÷ 13.1094 miles = 411.9 s = 6:52.
Per kilometre: 5,400 ÷ 21.0975 km = 256.0 s = 4:16.
At 10 km: 5,400 × 10 ÷ 21.0975 = 2,559.5 s = 42:40.
At 10 miles: 5,400 × 10 ÷ 13.1094 = 4,119.2 s = 1:08:39.
At 20 km: 5,400 × 20 ÷ 21.0975 = 5,119.1 s = 1:25:19.
Speed: 13.1094 miles ÷ 1.5 h = 8.74 mph (14.06 km/h).

Every split on this page uses one formula: goal seconds × distance covered ÷ race distance, rounded to the nearest second. A mile is 1.609344 km, so the half marathon is 13.1094 miles.

Checkpoints are even-pace clock times for the half marathon (21.0975 km / 13.11 mi), on mile markers or kilometre markers to match the toggle. Underlined times open that goal's page, with every split.

Where 1:30 sits in the field

RunRepeat's finish-time percentiles (35M results across 28,000+ races, as printed on our average half marathon time page) place 1:30:00 between the fastest 1% (1:23:59) and the fastest 10% (1:47:10) of all finishers. For men it sits between the fastest 1% (1:18:37) and the fastest 10% (1:40:35); for women, faster than the 1:35:55 that marks the fastest 1%.

Read the other way: 1:30 beats more than 90% of all finishers in that data, and a woman running it is faster than the 1:35:55 that marks the fastest 1% of women.

Neighbouring goals: 1:45 half marathon pace (8:01 per mile) and 2-hour half marathon pace (9:09). Every finish time from 1:20 to 2:45 is on the half marathon pace chart.

How to train for a sub-1:30 half marathon

Check the goal before you train for it. Riegel's formula, T2 = T1 × (D2 ÷ D1)^1.06 (Riegel, American Scientist 69(3), 1981), says 1:30:00 for the half marathon is worth:

10K: 5,400 × (10 ÷ 21.0975)^1.06 = 2,447 s = 40:47.
Marathon: 5,400 × (42.195 ÷ 21.0975)^1.06 = 11,259 s = 3:07:39.

The 10K figure is the useful check: a recent 10K near 40:47 is the evidence that 1:30 is within reach. The marathon figure assumes marathon training on top of half-marathon fitness, so read it as a best case. Run your own recent result through the race time predictor, and use the VDOT calculator to turn it into training paces.

Then pick a plan. Sub-1:30 is the advanced end of the half marathon: it asks for an established base and two quality sessions a week, which is what the advanced level assumes. The free 12-week advanced half marathon plan is 5 runs a week with two quality sessions, peaking at 55 km with a 23 km long run, with cutback weeks and a taper. If you are earlier in the climb, the intermediate 12-week plan runs four days a week.

Even splits are the reference line, not the plan

Nobody runs a perfect even split, and the opening of a half marathon feels easy at almost any pace. Use these times as the line you measure drift against: if you are well ahead early, you are spending the end of the race at the start.

Stop calculating. Start training.

Fair questions

What pace is a 1:30 half marathon?

6:52 per mile, or 4:16 per kilometre: 5,400 seconds ÷ 13.1094 miles = 411.9 s, and ÷ 21.0975 km = 256.0 s. You pass 10K at 42:40 and 20K at 1:25:19.

Is 1 hour 45 minutes a good time for a half marathon?

Yes, by the published numbers. RunRepeat's finish-time percentiles (35M results) put the fastest 10% of half marathon finishers at 1:47:10 or better, so 1:45 is inside the fastest 10%. A 1:30 is faster still, between the fastest 1% (1:23:59) and the fastest 10%.

What is the average pace for running a sub-2 hour half marathon?

9:09 per mile, or 5:41 per kilometre, passing 10K at 56:53.

What pace is a 1:35 half marathon?

7:15 per mile, or 4:30 per kilometre, passing 10K at 45:02.

What 10K time do you need for a 1:30 half marathon?

About 40:47 by Riegel's formula: 5,400 × (10 ÷ 21.0975)^1.06. That assumes you have done the long runs; without them, the half will come in slower.
