Frequently Asked Questions
What is a good running pace?
A good pace depends on your fitness level and goals. An average recreational runner runs a 5K at about 9–12 min/mile. Elite runners finish a 5K around 5 min/mile. For beginners, completing any distance is a win — pace matters less than consistency.
How do I convert min/mile to km/h?
Divide 60 by your pace in min/mile, then multiply by 1.60934. For example: 9 min/mile = 60/9 = 6.67 mph × 1.60934 = 10.73 km/h. This calculator shows both automatically in the results.
