Question 1

What pace do I need to run a sub 3 hours 18 minutes marathon?

Accepted Answer

To finish a marathon (26.2 miles / 42.2 km) in under 3:18:00, you need to average 7:33 per mile — that's 4:42 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 3:18 marathon?

Accepted Answer

Running an even 7:33 per mile, you'd pass mile 1 at 7:33, reach halfway in about 1:39:00, and cross the finish line in 3:18:00. 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 3:18 marathon a good time?

Accepted Answer

Finishing a marathon in sub 3 hours 18 minutes is a solid recreational result that reflects consistent training. Practicing 7:33 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.
