Running pace calculator: pace, time and race splits
Pace is time divided by distance. Enter a distance and your time to get pace per kilometre and per mile, plus what that pace means for a 5K, 10K, half marathon and marathon. Longer races are usually run slower than the same pace, so treat long-distance times as the fastest case.

Questions
What is a good 5K pace for a beginner?
Anything you can hold while breathing hard but controlled. Many new runners finish 5K in 30 to 40 minutes, about 6 to 8 minutes per km.
How do I get faster?
Mostly easy running, plus one session a week of faster intervals or tempo. Increase weekly distance gradually.
Should easy runs be slow?
Yes. Easy runs at a conversational pace build aerobic fitness with less fatigue.
