Frequently Asked Questions
How do I calculate my running pace?
Divide your total time (in seconds) by the distance you ran. For example, if you ran 5 km in 25 minutes (1,500 seconds), your pace is 1,500 ÷ 5 = 300 seconds per km, which equals 5:00 per km. To convert to per-mile pace, multiply by 1.60934.
What's a good pace for a 5K or marathon?
For a 5K, beginners often finish around 8–10 min/mile (5–6:12 min/km), intermediate runners target 7–8 min/mile (4:21–5:00 min/km), and competitive runners aim for sub-6 min/mile (sub-3:44 min/km). For a marathon, a sub-4-hour finish requires roughly 9:09 min/mile (5:41 min/km), while elite runners push below 5 min/mile (3:06 min/km).
How do I convert pace per mile to pace per km?
To convert min/mile to min/km, divide by 1.60934. For example, an 8:00/mile pace equals 8 × 60 = 480 seconds ÷ 1.60934 ≈ 298 seconds = 4:58/km. To go the other way (min/km to min/mile), multiply by 1.60934.
