Frequently Asked Questions
How do I calculate running pace?
Pace = time ÷ distance. A 5 km run in 25 minutes is a 5:00 min/km pace. Divide total seconds by km (or miles) to get per-unit pace.
What's a good 5K pace?
Recreational runners: 6:00–7:00 min/km (30–35 min). Fit runners: 5:00 min/km (25 min). Sub-20 minute 5K = 4:00 min/km — competitive amateur level.
How fast is a 4-hour marathon?
42.195 km in 240 min = 5:41 min/km pace (9:10 min/mile). That's about 10.5 km/h.
Min/km to min/mile?
Multiply min/km by 1.609. So 5:00 min/km = 8:03 min/mile. 6:00 min/km = 9:39 min/mile.
