Take the quizPacing a 10K
A 10K (6.21371 miles) rewards patience more than a 5K does. Going out at your goal pace and holding it — rather than banking early time you can't sustain — is the more reliable strategy at this distance.
Use the pace calculator to check your equivalent pace in the other unit, or the race time predictor to see how a 10K fitness level translates to other distances.
Where these numbers come from
The formulas and default values in this calculator are based on:
- Official 10K race distance (10 kilometers = 6.21371 miles)
These are planning estimates for training purposes. Check with a coach, trainer, or physician before starting a new program or maxing out.
Frequently asked questions
How is 10K pacing different from 5K pacing?
A 10K is long enough that an even or slightly negative split tends to outperform an aggressive start by a wider margin than in a 5K, since there's more time to pay for early mistakes.
What pace should my training runs be relative to 10K race pace?
Most easy runs are run noticeably slower than 10K race pace, with only specific workouts (tempo runs, intervals) approaching or exceeding it.
Can I use my 5K time to predict my 10K pace?
Roughly, yes, though most runners slow slightly per mile as distance increases. The race time predictor accounts for that using the Riegel formula.
