Question 1

What pace do I need to run a sub 1 hour 13 minutes half marathon?

Accepted Answer

To finish a half marathon (13.1 miles / 21.1 km) in under 1:13:00, you need to average 5:34 per mile — that's 3:28 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 1:13 half marathon?

Accepted Answer

Running an even 5:34 per mile, you'd pass mile 1 at 5:34, reach halfway in about 36:30, and cross the finish line in 1:13:00. 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 1:13 half marathon a good time?

Accepted Answer

Finishing a half marathon in sub 1 hour 13 minutes is a highly competitive result that puts you near the front of most fields. Practicing 5:34 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.
