- •Marathon pace (avg runner): 5:00–5:30 min/km (3:30–4:00 finish)
- •Half marathon: 4:30–5:00 min/km
- •10K race pace: 4:00–4:30 min/km
- •5K race pace: 3:30–4:30 min/km

How running pace is calculated
Pace = time per km. Convert between pace and total time/distance using simple ratios.
- 1
Calculate pace per km
Pace_per_km = total_seconds ÷ km
Convert: 300 seconds = 5:00 min/km.
- 2
Convert pace to speed
Speed_kmh = 3600 ÷ pace_seconds_per_km
5:00/km = 12 km/h.
- 3
Predict time for distance
Time = pace_per_km × distance_km
Marathon at 5:00/km = 3:30:34 finish.
Worked example
Inputs: Run 10km in 50:00
Result: Pace = 5:00/km. Speed = 12 km/h.
Frequently Asked Questions
How do I calculate my running pace?
What are typical NZ 5km and 10km race times?
How does altitude affect running pace in NZ?
What is the Parkrun NZ average time?
Converts between running speed, pace, and time for NZ runners. Calculates pace (min/km), speed (km/hr), and estimated finish times for common NZ race distances: 5km parkrun, 10km, half marathon (21.1km), and full marathon (42.2km).
How this calculator works
Pace (min/km) = time in minutes / distance in km. Speed (km/hr) = 60 / pace (min/km). Estimated finish time = pace (min/km) x distance in km.
Common NZ Running Distances and Benchmarks
| parkrun (5km) | Average NZ finisher: ~28-30 min |

Worked Examples
5km in 25 minutes
Pace 5:00/km, speed 12.0 km/hr.
- Pace = 25 min / 5 km = 5:00 min/km
- Speed = 60 / 5.0 = 12.0 km/hr
- Estimated 10km time at same pace: 5:00 x 10 = 50:00 min
- Estimated half marathon: 5:00 x 21.1 = 105:30 (1hr 45:30)
Marathon in 4 hours
Pace 5:41/km, speed 10.55 km/hr.
- Total time: 4 x 60 = 240 minutes
- Pace = 240 / 42.2 = 5.687 min/km = 5:41/km
- Speed = 42.2 / 4 = 10.55 km/hr
