What is the difference between pace and speed?

Pace is time per distance (e.g., 5:00 min/km) — how long it takes to cover a unit of distance. Speed is distance per time (e.g., 12 km/h) — how much distance you cover in a unit of time. Runners typically use pace; cyclists and drivers use speed.

How do I convert between min/km and min/mile?

Multiply min/km by 1.60934 to get min/mile, or divide min/mile by 1.60934 to get min/km. For example, 5:00 min/km ≈ 8:03 min/mile. This converter handles the math and also shows projected finish times for common race distances.

What is a good running pace?

It depends on experience, age, and goals. A beginner might run 7:00-8:00 min/km (11:15-12:50 min/mile). Intermediate runners target 5:00-6:00 min/km (8:00-9:40 min/mile). Competitive runners aim for under 4:00 min/km (6:26 min/mile). Elite marathoners run ~2:55 min/km.

Why do races use different distance units?

Most of the world uses kilometers, but the U.S. commonly uses miles. The marathon (42.195 km / 26.219 mi) is a fixed distance. 5K, 10K, and half-marathon are metric; some U.S. races use mile-based distances. This converter gives splits for all common distances.

Understanding Pace

Running pace is usually expressed as minutes:seconds per kilometer or per mile. A pace of 5:30/km means it takes you 5 minutes and 30 seconds to run each kilometer. Faster runners have lower pace numbers.

Race Splits

This converter shows projected finish times for 5K, 10K, half-marathon, marathon, and other distances based on your pace. These assume even pacing — running each kilometer at the same speed. In practice, most runners slow slightly in the second half (positive split).

Projected finish times assume even pacing on flat terrain. Actual race times will vary based on elevation, weather, fatigue, and race-day strategy.
