Running Pace Calculator

Calculate your running pace, finish time, or distance. Perfect for training and race planning for 5K, 10K, half marathon, and marathon distances.

Pace = Time ÷ Distance; Time = Distance × Pace; Distance = Time ÷ Pace. Speed (mph) = 60 ÷ Pace (min/mile)
Running 5 miles in 45 minutes: Pace = 45 ÷ 5 = 9:00 min/mile pace (6.67 mph). Marathon at 9 min/mile = 3:56:24 finish time

What is a good running pace?

Beginner runners average 12-15 minutes per mile. Intermediate runners: 9-11 min/mile. Advanced: 7-9 min/mile. Elite marathoners run sub-5 min/mile pace. Your ideal pace depends on distance, fitness level, and goals.

How do I calculate my running pace?

Divide your total time by the distance covered. For example, if you run 3 miles in 27 minutes: 27 ÷ 3 = 9 minutes per mile pace. To convert to per kilometer, divide total time by distance in km.

What pace should I run a marathon?

Most runners aim for a pace they can sustain comfortably. A common strategy is to run your long training runs 30-90 seconds per mile slower than goal marathon pace. For your first marathon, aim to finish comfortably rather than chase a time.

How do I convert pace to speed?

Speed (mph) = 60 ÷ pace (minutes per mile). For example, a 10 min/mile pace = 60 ÷ 10 = 6 mph. To convert to km/h, multiply mph by 1.60934. A 10 min/mile pace equals approximately 9.7 km/h.
