Half Marathon Pace Chart: Splits, Finish Times, and Goal Pace Guide
Use this half marathon pace chart to convert goal time to pace, pace to finish time, and compare practical kilometer and mile checkpoints for common half marathon targets.
What does this half marathon pace chart help you do?
This page lets you move between goal half-marathon time and goal pace without doing the math by hand. Use it to answer practical questions like what pace is a 2-hour half marathon, what your halfway split should look like, and how to compare pacing options before race day.
All calculations use the full official half-marathon distance of 21.0975 kilometers. The chart assumes even pacing, but the execution notes below explain why patience in the first 3-5K still matters.

Quick coaching note
Stay controlled through the first 3-5 kilometers, settle into sustainable rhythm, and avoid chasing pace if wind, hills, or fueling issues start to push effort upward after 10 miles.

Pacing interpretation
This is a common benchmark range. Most runners do better by settling after the opening 3-5K than by forcing goal pace immediately.
Stay controlled through the first 3-5 kilometers, settle into sustainable rhythm, and avoid chasing pace if wind, hills, or fueling issues start to push effort upward after 10 miles.
Mile-based cumulative splits are calculated from the exact pace before display rounding, so the final mile checkpoint can differ by a second from multiplying the rounded pace label.

How to use the half marathon pace chart
Choose a target with durability in mind
A half marathon rewards runners who can hold pace after the early adrenaline is gone. Pick a row that matches your current aerobic durability, not just your shortest-race speed.
Use overview for the big picture
The overview tab gives you finish time, pace per kilometer, pace per mile, and halfway split. That is the fastest way to pressure-test whether a target looks realistic.
Use checkpoints for race-day control
The kilometer and mile tabs focus on the checkpoints that tend to matter most in a half marathon: early control, mid-race rhythm, and whether pace drift appears late.
Half marathon pace per mile vs pace per kilometer
A half marathon is 21.0975 kilometers, which is about 13.1094 miles in exact conversion terms. Many runners still describe the race as “13.1 miles,” which is fine conversationally, but using the full distance keeps pace calculations more precise.
Stick with the unit you naturally use in training. The best race-day pace target is the one you can recognize quickly when the effort starts to rise.
Common half marathon goal examples
Sub-1:30 half
You need about 4:16 per kilometer or 6:52 per mile. That pace rewards disciplined opening miles and stable effort through the middle of the race.
Sub-2:00 half
You need about 5:41 per kilometer or 9:10 per mile. This is one of the most common target zones, and the main threat to it is usually early pace drift rather than lack of grit late.
Sub-2:30 half
You need about 7:07 per kilometer or 11:27 per mile. For many newer half-marathoners, that goal is best protected by calm opening miles and steady fueling or hydration habits.
How to pace a half marathon
A half marathon usually rewards steadiness more than aggression. Observational research such as Nikolaidis and Knechtle and Nikolaidis et al. suggests half-marathon pacing is often more even than marathon pacing, but it still deteriorates when runners start above sustainable effort.
- Keep the first 3-5K controlled enough that you can still settle smoothly into race rhythm.
- Use the middle third of the race to protect consistency, not to chase time you did not need to lose.
- Watch for pace drift after 10 miles and judge effort honestly before trying to squeeze the closing miles.
- If conditions are difficult, protect effort first and pace second.
Common half marathon pacing mistakes
- Running the first 3 miles at pace that feels fun but is not actually sustainable.
- Ignoring whether your current training supports steady effort past 10 miles.
- Using a pace target from old fitness rather than recent racing or long workouts.
- Waiting too long to hydrate or fuel on a day where conditions raise effort.
- Assuming the chart is a guarantee rather than a pacing framework.
How weather, hills, and course profile affect half marathon pace
A half marathon sits in the awkward zone where runners often feel strong enough to ignore conditions but are still exposed to meaningful pace drift when the course or weather is harder than expected.
If the route is windy, warm, or rolling, it is usually safer to protect rhythm in the first half and let the outcome be determined by how well you hold effort late rather than by how aggressively you start.
How to choose a realistic half marathon goal time
Start with your recent 10K or longer-race evidence, your long-run durability, and how well you can hold pace through extended threshold-style work. If you are between chart rows, the slower row is usually the more stable first choice.
For broader context, pair this chart with the half marathon running times guide and the Race Strategy Calculator.
Methodology
Time from pace
Half marathon finish time = pace per km × 21.0975
If your pace is 5:41 per kilometer, your projected half marathon finish is about 2:00:00.
Time from mile pace
Half marathon finish time = pace per mile × 13.1094
If your pace is 9:10 per mile, your projected half marathon finish is about 2:00:00.
Pace from finish time
Pace per km = finish time ÷ 21.0975
A 1:45:00 half marathon equals about 4:59 per kilometer.
Mile conversion
Pace per mile = finish time ÷ 13.1094
A 1:45:00 half marathon equals about 8:01 per mile after rounding.
This page uses the full official half-marathon distance for pace conversion, chart generation, and checkpoint math. Mile-based checkpoints are calculated from exact pace before display rounding to keep the finish-time logic consistent.
Frequently asked questions
What pace is a 2-hour half marathon?
A 2:00:00 half marathon requires about 5:41 per kilometer or 9:10 per mile. It is one of the most common benchmark goals because it is ambitious but still practical for many trained recreational runners.
Should I run even splits in a half marathon?
For most runners, even pacing or a slight negative split is a strong default. The biggest practical mistake is usually drifting too fast through the first 3-5K and paying for it after 10 miles.
Why are there fewer kilometer checkpoints than on the 10K page?
For longer races, checkpoint tables become easier to use when they focus on decision points like 5K blocks and major mile markers instead of every single split.
Does this page use the full official half marathon distance?
Yes. Calculations use the official half marathon distance of 21.0975 kilometers, not a shortened approximation.
Why can the finish mile checkpoint differ by a second from the pace label?
Displayed pace labels are rounded for readability, but mile-based cumulative checkpoints are still calculated from exact pace. That can create a one-second difference at the end of the race.
