Formulas Used

Pace (min/mile)

pace_min_part = floor(pace_per_mile)

Pace (sec remainder)

pace_sec_part = round((pace_per_mile - floor(pace_per_mile)) * 60)

Pace (min/km)

pace_per_km = round(total_minutes / 10 * 100) / 100

Average Speed

speed_mph = round(6.21371 / (total_minutes / 60) * 100) / 100

How It Works

How 10K Pace Is Calculated

A 10K is 10 kilometers or 6.21371 miles.

Formula

Pace (min/mile) = Total Time (minutes) / 6.21371

Training for a 10K

The 10K demands both speed and endurance. Typical preparation includes tempo runs, interval sessions, and long runs of 8-10 miles. Your 10K pace is roughly 20-30 seconds per mile slower than your 5K pace.

Worked Example

You want to finish a 10K in 55 minutes.

target_minutes = 55target_seconds = 0
  1. 01Total time = 55 minutes
  2. 02Pace = 55 / 6.21371 = 8.85 min/mile
  3. 03That is 8 minutes and 51 seconds per mile
  4. 04Pace per km = 55 / 10 = 5.50 min/km
  5. 05Speed = 6.21371 / (55/60) = 6.78 mph
