Run Pace 40-Minute 10K Pace
Required pace: 4:00 /km · 6:26 /mileFinish time 40:00
Forty minutes is the 10K time that marks a genuinely quick club runner. The arithmetic is tidy, 4:00 per kilometre and 20:00 at halfway, but holding it means running close to your threshold for the full distance.
Most runners who break 40 can already run a 5K in about 19 minutes. Check the equivalent race times below before you set out at this pace.

Frequently asked questions
What pace is a 40-minute 10K?
A 40:00 10K is exactly 4:00 per kilometre, which is about 6:26 per mile.
What 5K time do I need for a sub-40 10K?
The Riegel formula pairs a 40:00 10K with a 5K of about 19:11. A 5K closer to 18:45 gives you a little margin for a windy or crowded race.
What training helps most for a 40-minute 10K?
Intervals of 1 to 2 km at or slightly faster than 4:00 per kilometre, a weekly tempo run and an easy long run of 14 to 18 km cover most of what you need.
