What Is a Good 400m Time?

August 12, 2026 · 7 min read

The 400 is the event where the number lies to you most often, because two athletes can run the same time in completely different ways and only one of them has room to improve.

The published ranges

These come from published college recruiting standards, not from an average.

NCAA Division I: boys about 46.10 at the top to 49.00 at the bottom. Girls about 52.20 to 57.00.
NCAA Division II: boys about 47.40 to 50.10. Girls about 54.90 to 59.60.
NCAA Division III: boys about 47.90 to 52.00. Girls about 55.60 to 61.30.
NAIA: boys about 48.60 to 50.90. Girls about 56.80 to 59.60.

Read those bottom numbers rather than the top ones if you are working out where you stand. For a boy, anything under about 52 seconds is inside a published band somewhere, under 50 has most divisions live, and under 49 opens D1. For a girl, under about 61 seconds is inside a band, under 59 has most divisions live, and under 57 opens D1.

The number is not the whole story

Coaches look at how the 400 was run, not just what it came out at.

Your split differential. Take your first 200 and your second 200. A well-run 400 usually has a second half about one to one and a half seconds slower than the first. If your differential is three seconds, you went out far too hard, and there is a faster time in you at the same fitness. If it is under a second, you were too conservative.

What your 200 says. A boy running 22.5 for 200 and 52 for 400 has an endurance problem, not a speed problem. The same boy running 24.0 and 52 has the opposite. Those two athletes need completely different training, and a coach can tell them apart from a results page.

Season shape. The 400 responds to training more visibly than almost any other event. Coaches know that, so a big in-season drop reads as coachability.

If you want to get faster at it

The honest version: the 400 is limited by your ability to hold speed while lactate accumulates, which is trained by running fast repeats over 150 to 300 meters with incomplete recovery. It is also limited by top speed, which is why 400 runners do 60m work.

That said, take training prescriptions from your own coach, who can see you run. Anything specific you read online is written for an athlete who is not you.

Get it timed properly

A hand-timed 400 conventionally has 0.14 added, not the 0.24 used for shorter sprints, because reaction error is a smaller fraction of a longer race. Whichever way, know which one you are quoting when you email a coach.

You can check any 400 time against all four divisions on the standards page, or read the ladder directly for boys and girls.
