This calculator converts between time, distance, and pace for running or walking — solve for any one of the three when you know the other two. Useful for race planning, training pace targets, or converting between pace-per-km and pace-per-mile.
Example: covering 5 km in 50 minutes 25 seconds works out to a pace of roughly 10:05 per km — switch between distance units and solve for time, distance, or pace depending on what you're planning.
Pace is the time it takes to cover a unit of distance — typically expressed as minutes per kilometer or minutes per mile. It is the most common way runners measure and compare their performance.
Pace = Time ÷ Distance. Speed = Distance ÷ Time. Distance = Speed × Time. If you know any two values, the calculator computes the third automatically.
Popular distances include 5K, 10K, half marathon (21.1 km), and full marathon (42.2 km). Training at varied paces — easy runs, tempo runs, and intervals — improves overall race pace over time.
Even splits means maintaining a consistent pace throughout. Negative splits means running the second half faster — a strategy associated with stronger race performances.

Yes — just adjust your expected pace for the activity type, since walking, running, and cycling naturally have very different pace ranges (e.g. a 12:00/km walking pace vs a 4:00/km cycling pace).
