Question 1

What pace do I need to run a sub 20 minutes 30 seconds 5K?

Accepted Answer

To finish a 5K (3.1 miles / 5 km) in under 20:30, you need to average 6:36 per mile — that's 4:06 per kilometer. The split table on this page shows the exact cumulative time to hit at every mile marker along the way.

Question 2

What are the mile splits for a sub 20:30 5K?

Accepted Answer

Running an even 6:36 per mile, you'd pass mile 1 at 6:36, reach halfway in about 10:15, and cross the finish line in 20:30. Prefer to finish faster than you start? Switch the calculator above to negative split to see per-mile targets that start slower and speed up.

Question 3

Is a sub 20:30 5K a good time?

Accepted Answer

Finishing a 5K in sub 20 minutes 30 seconds is a solid recreational result that reflects consistent training. Practicing 6:36 per mile in training — on tempo runs, race-pace intervals, and long runs — is the most direct way to make this goal feel routine on race day.
