Calculate your 10 mile pace, finish time and splits
The 10 Mile Pace Calculator converts between a target finish time and the pace required to achieve it. Enter either your planned time or target pace to calculate pace per mile, pace per kilometre, average speed and cumulative race splits.
You can compare even pacing with a negative-split strategy, generate kilometre or mile split tables, print or save the plan as a PDF, download the results as CSV and create a shareable result.
How to use the 10 Mile Pace Calculator
- Choose whether to calculate from a target finish time or target pace.
- Enter the time or pace you want to use.
- Select even pacing or a negative split.
- Choose kilometre or mile splits.
- Calculate, then print, download or share the result.
Worked example: an 80-minute 10 mile race
An even-paced target of 1:20:00 requires approximately:
| Metric | Result |
|---|---|
| Pace per mile | 8:00 |
| Pace per kilometre | 4:58 |
| Average speed | 12.1 km/h |
| 5K | 24:51 |
| 5 miles | 40:00 |
| 10K | 49:43 |
| 15K | 1:14:34 |
| 10 miles | 1:20:00 |
These times assume continuous running at an even pace. Add any expected delays from congestion, sharp turns, hills or aid stations when setting the final race target.
Even pace versus negative split
Even pacing uses the same planned pace throughout the race. It is simple to follow and works well on flat courses with predictable conditions.
Negative splitting starts slightly slower and finishes faster. This can reduce the risk of overcommitting early, but only when the faster second half is realistic for your fitness and the course profile.
Use the calculator’s negative-split options to compare strategies before race day rather than improvising after the start.
How the 10 mile distance compares
Ten miles equals approximately 16.093 kilometres. It is 6.093 km longer than a 10K and about 5.004 km shorter than a half marathon.
The distance rewards a balance of speed and endurance. It is long enough for pacing errors to accumulate, but short enough that many runners can sustain a stronger effort than they would over a half marathon.
Practical 10 mile race planning
- Use the opening mile to settle into target effort rather than chasing seconds immediately.
- Check the five-mile split as the clearest halfway reference.
- Adjust pace for hills, wind, heat and crowded sections.
- Use effort as well as watch pace when the course is not flat.
- Treat the final two miles as the point to increase effort when the planned pace still feels controlled.

Frequently Asked Questions
What pace is an 80-minute 10 mile race?
An 80-minute finish requires 8:00 per mile, approximately 4:58 per kilometre.
How far is 10 miles in kilometres?
Ten miles equals approximately 16.093 kilometres.
What is the halfway split for a 10 mile race?
The halfway point is five miles. For an 80-minute target, the even-paced halfway split is 40:00.
Is even pacing or a negative split better?
Neither is universally better. Even pacing is simpler, while a controlled negative split can reduce early overexertion. Course profile and fitness should guide the choice.
How do I print or download the pace chart?
After calculating the plan, use the print or PDF option, download the split table as CSV, or create a shareable result.
