This calculator computes running pace in minutes per kilometre (min/km) and speed in km/h based on distance and running time. The result is shown both as a decimal number and in the readable mm:ss min/km format. Perfect for runners planning races and training sessions.
Formulas: 1. pace_min_km = time_minutes / distance_km 2. speed_kmh = distance_km / (time_minutes / 60) 3. mm:ss format: minutes = floor(pace), seconds = round((pace - minutes) × 60) E.g. pace = 5.5 → 5 minutes and round(0.5 × 60) = 30 seconds → 5:30 min/km
For a distance of 10 km and a time of 55 minutes: • Pace = 55 / 10 = 5.5 min/km
5:30 min/km • Speed = 10 / (55/60) ≈ 10.91 km/h A runner at this pace would finish a marathon (42.195 km) in approximately 3 hours 52 minutes.
Running pace is the time needed to cover one kilometre, expressed in minutes per kilometre (min/km). It is calculated by dividing total running time (in minutes) by distance (in km). For example, 60 minutes for 10 km gives a pace of 6:00 min/km.
Pace (min/km) tells you how long it takes to cover one kilometre — the lower the pace, the faster you run. Speed (km/h) is the inverse — how many kilometres you cover in one hour. Formula: speed = 60 / pace. E.g. pace 6:00 min/km = speed 10 km/h.
Typical paces for beginners: 7–9 min/km (about 7–9 km/h). Intermediate runners manage 5–7 min/km, advanced amateurs achieve 4–5 min/km. Elite marathon runners race below 3 min/km.
Pace (min/km) = time_minutes / distance_km. For example, running 10 km in 55 minutes: pace = 55 / 10 = 5.5 min/km, which corresponds to 5:30 min/km. The calculator shows the result both as a decimal and in mm:ss format.
Speed (km/h) = 60 / pace (min/km). E.g. pace 5:00 min/km → speed = 60 / 5 = 12 km/h. Conversely: pace = 60 / speed. E.g. speed 10 km/h → pace = 60 / 10 = 6:00 min/km.
Amateur benchmarks: 5K in 25 min = 5:00 min/km; 10K in 50 min = 5:00 min/km; half marathon in 1:50 h = 5:13 min/km; marathon in 4 h = 5:41 min/km. The world marathon record corresponds to approximately 2:51 min/km.
The calculator uses: pace_min_km = time_minutes / distance_km, then converts to mm:ss format (minutes:seconds per km). Speed is calculated as: km/h = distance_km / (time_minutes / 60).
Yes — endurance training runs are typically 1–2 min/km slower than race pace. Training at a lower pace builds aerobic base and reduces injury risk. Race pace should be planned in advance and maintained evenly throughout the run.
Improve pace through: speed intervals (short efforts at high intensity), easy aerobic runs (long runs at slow pace), strength and core training, and adequate recovery. Progress is gradual — typically 10–30 seconds per km over several months of consistent training.
The tempo_min_km value is pace expressed as a decimal, e.g. 5.5 means 5 minutes and 30 seconds per km (5:30 min/km). The calculator also shows the result in the readable mm:ss format, e.g. '5:30 min/km'. Speed is shown simultaneously in km/h.
