How to Calculate Running Pace

Whether you are taking your first steps toward completing a couch-to-5K program or aiming for a Boston Marathon qualifying time, running pace is the fundamental metric of endurance running. Pace measures how many minutes and seconds it takes you to cover a specific unit of distance (either one kilometer or one mile).

The Running Pace Formula

Pace is simply elapsed time divided by distance:

Pace = Total Elapsed Time ÷ Total Distance Traveled

Step-by-Step Pacing Calculation

Suppose an athlete finishes a 10-kilometer road race in 52 minutes and 30 seconds. What was their average pace per kilometer?

1. Convert time into decimal minutes:
   52 minutes + (30 seconds ÷ 60) = 52.5 minutes.
2. Divide by distance:
   52.5 minutes ÷ 10 km = 5.25 minutes per kilometer.
3. Convert decimal fraction back into seconds:
   0.25 minutes × 60 seconds = 15 seconds.
   Average Pace: 5:15 min/km.

Converting Pace Between Kilometers and Miles

Because 1 mile equals approximately 1.60934 kilometers, running 1 mile takes 1.60934 times longer than running 1 kilometer at the same speed:

• A 5:00 min/km pace equals approximately 8:03 min/mile.
• A 6:00 min/km pace equals approximately 9:39 min/mile.

Common Race Distances

• 5K: 5.0 kilometers = 3.107 miles
• 10K: 10.0 kilometers = 6.214 miles
• Half Marathon: 21.0975 kilometers = 13.109 miles
• Marathon: 42.195 kilometers = 26.219 miles
