Frequently Asked Questions
What is a good running pace for beginners?
A good beginner running pace is between 7:00–9:00 min/km (11:00–14:30 min/mile). The most important thing is to run at a conversational pace — you should be able to speak in short sentences without gasping.
How do I convert pace to speed?
Divide 60 by your pace in minutes. A pace of 5:00 min/km equals 60 ÷ 5 = 12 km/h. For min/mile to mph, divide 60 by the pace in decimal minutes. This calculator handles it instantly.
What pace do I need for a sub-2 hour half marathon?
You need a pace faster than 5:41 min/km (9:09 min/mile) — equivalent to 10.55 km/h (6.55 mph). Use the Target Pace tab above: set goal to 1:59:59 and distance to 21.097 km.
What pace is a 4 hour marathon?
A 4-hour marathon requires a steady 5:41 min/km (9:09 min/mile) for all 42.195 km. Many runners aim to negative split — run the first half ~1 min/km slower, then accelerate.
What is the difference between pace and speed?
Pace = time per unit of distance (e.g. 5:30 per km). Speed = distance per unit of time (e.g. 10.9 km/h). Runners use pace; cyclists use speed. They're inverses of each other — faster pace = higher speed.
