10K Pace Calculator

Convert a 10K goal time into per-kilometer or per-mile pace, then compare it with race equivalents and interval split targets.

Interval targets based on your equivalent 5K effort.

1Use the goal buttons to compare 10K targets from 35 minutes through 65 minutes.
2Check the 5K equivalent if you are sharpening speed before a longer race block.
3Switch units when you need both metric splits and mile-based training paces.

Goal	Pace	Use case
35 minute 10K	3:30/km or 5:38/mi	A fast benchmark for competitive recreational runners.
40 minute 10K	4:00/km or 6:26/mi	A widely searched 10K milestone.
50 minute 10K	5:00/km or 8:03/mi	Simple to track with metric splits.
60 minute 10K	6:00/km or 9:39/mi	A common first-race target.

What pace is a 50 minute 10K?

A 50 minute 10K is exactly 5:00 per kilometer, or about 8:03 per mile.

How do I pace a 10K evenly?

Start close to goal pace for the first 2-3 kilometers, settle through the middle, then increase effort if you are still controlled late in the race.

Can I convert 10K pace to marathon pace?

You can estimate an equivalent marathon result, but the marathon requires more endurance and fueling, so treat it as a guide rather than a guarantee.
