Running Pace Calculator

What running pace actually means

Your pace is how long it takes to cover one unit of distance, written as minutes and seconds per kilometre or per mile. A pace of 6:00 /km means every kilometre takes six minutes. It is the mirror image of speed: where speed answers "how fast," pace answers "how long per km," which is far more useful when you are pacing a run in real time. Most training plans, races, and treadmills talk in pace, so it is worth getting comfortable reading it.

How to use pace when you are starting out

If you are new to running, resist the urge to chase a fast number. The most common beginner mistake is starting too quickly, running out of breath in the first two minutes, and deciding that running "isn't for them." It almost always is; the pace was just wrong. Use this calculator to sanity-check a goal: enter 5K and a finish time you have in mind, then look at the pace it demands. If that pace feels like a sprint, ease off. A realistic first 5K for many beginners sits somewhere between 7:00 and 9:00 per kilometre, and plenty of that early distance is walked. That is not cheating; it is exactly how run/walk training works.

Why conversational pace matters more than speed

The pace that builds fitness fastest for a beginner is slower than you would think. A good rule: you should be able to speak a full sentence out loud while running. If you can only gasp a word or two, you are going too hard. This "conversational pace" keeps you in an aerobic zone where your body actually adapts and, just as importantly, where running stays pleasant enough that you come back for the next session. Speed comes later, almost on its own, once the habit is in place.

Pace turns walking and short run intervals into your first continuous 5K, three guided workouts a week. If you want the plan that goes with the numbers, see how Pace works or read the beginner running blog.
