Question 1

What pace do I need to run a sub 18 minutes 30 seconds 5K?

Accepted Answer

To finish a 5K (3.1 miles / 5 km) in under 18:30, you need to average 5:57 per mile — that's 3:42 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 18:30 5K?

Accepted Answer

Running an even 5:57 per mile, you'd pass mile 1 at 5:57, reach halfway in about 9:15, and cross the finish line in 18:30. 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 18:30 5K a good time?

Accepted Answer

Finishing a 5K in sub 18 minutes 30 seconds is a strong age-group result, ahead of most recreational runners. Practicing 5:57 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.
