Pace chart: Half marathon
Every row is computed by the calculator above. The pace is rounded down to the second, so running it gets you to the half marathon finish at or just under the goal.

How the chart is built
Every row divides the goal time by 21.0975 km - half of the marathon, not the
rounded 21.1 - converts it to miles with the exact international mile, and
rounds the pace down to the second. The last column shows the finish that
rounded pace delivers, which is never slower than the goal.
Using the splits
The 5K, 10K and 15K columns are even-pace checkpoints. Coming through 10K
within a few seconds of the chart is a good sign; a minute ahead usually means
the last 5K will be the slowest of the day.
Other goals
The chart steps every 10 minutes. For anything in between, enter your goal in
the calculator above and it will print the pace and the full set of mile splits.

For runners in the US
The half is the most-run long race in the US, and for many runners it is the first race where pacing matters more than just finishing: at 13.1 miles, a first 5K run 20 seconds per mile too fast is still being paid for at mile 11. The chart gives mile pace first because that is what US courses mark.
Questions
What pace is a 2-hour half marathon?
9:09 per mile, or 5:41 per kilometer. Held for the full 21.0975 km, 5:41 per kilometer finishes in 1:59:54.
Is a half marathon 13.1 miles?
It is 13.109 miles - exactly half of 42.195 km. For a 2-hour goal the rounding moves the pace by less than half a second per mile, so it is harmless; the calculator uses the exact figure anyway.
