Frequently Asked Questions
What is a good running pace?
A good pace depends on your fitness level and goal. For recreational runners, 5:00–7:00 /km is typical. Competitive runners aim for 3:30–5:00 /km. Beginners often start at 7:00–9:00 /km.
How do I convert pace to speed?
Speed (km/h) = 60 ÷ pace (min/km). For example, a 5:00 /km pace = 60 ÷ 5 = 12 km/h.
What pace should I run to finish a marathon in 4 hours?
A 4-hour marathon requires a pace of approximately 5:41 /km (9:08 /mile). This calculator can work backwards from any finish time to find your target pace.
