How to Run a 400m Race: Pacing Strategy for Beginners

To run a good 400m, go out fast but controlled, hold your speed through the back straight and spend what you have left on the final 100 metres. Almost every runner slows in the last part of the race; the winner is usually the one who slows least. Beginners most often go out too hard, run out of energy on the final bend and lose far more time than they gained at the start.

The race is one lap of the track, run in lanes, and it sits between pure sprinting and middle-distance running. That is what makes pacing so important.

What you need

• A standard 400m track (or a measured lap)
• Spikes or flat racing shoes, plus a pair of normal trainers for warm-up
• A stopwatch or a friend to call times at the 200m mark
• A coach or experienced club member if you plan to use starting blocks

Step 1: Understand the stagger

In a 400m race each athlete stays in an assigned lane for the full distance. The outer lanes cover a longer curve, so their start lines are placed further forward. Standing in lane 8, you will not see the runners in lanes 1 to 3 until the final straight, and the reverse is true for them. The sensible response is to run your own race rather than chase what you can see.

Common mistake: sprinting to catch the runner ahead on the first bend. That runner started in a staggered position, so you are not really behind.

Step 2: Start and build speed

From the gun, accelerate for roughly the first 50 to 60 metres. Keep your head low at first and rise gradually, rather than standing up immediately. If you are not yet confident in blocks, a standing or rolling start in training is fine. Aim to reach about 90 to 95 percent of your maximum, not 100, so you can hold form later.

Step 3: Float through the first bend

Run relaxed on the first curve, with shoulders loose and hands soft. Think “fast but easy”. This is where beginners burn energy they cannot recover. Keep your stride long rather than short and choppy.

Step 4: Hold on the back straight

Between about 150m and 300m the aim is rhythm. Keep your head still, drive your arms and avoid tension in the jaw and neck. Many coaches describe this as the part of the race where you “stay tall” and keep the hips under you.

Step 5: Run the final bend and straight

By 300m, lactic acid and fatigue arrive. Your form is more important than your effort now: lift the knees, keep the arms driving, look ahead to the line and do not let the shoulders rise. The last 100m will feel slow even if you are working harder than ever. That is normal.

A worked pacing example

Suppose a beginner runs 400m in 70 seconds. A common pattern is a first 200m that is about 1.5 to 3 seconds quicker than the second, so something like 34 seconds followed by 36. If the same runner goes out in 31 seconds, the second half may collapse to 40 or more, giving a worse total. Even pacing in terms of effort, with a mild natural slowdown, usually produces the best time. The exact split depends on the athlete, so treat the numbers as an illustration, not a prescription.

Training for the 400m

• Tempo runs: 150 to 300 metres at a controlled pace with full recovery, teaching rhythm.
• Repeat 200s: a few efforts at near race pace with several minutes rest.
• Speed work: short sprints of 30 to 60 metres to develop top-end speed.
• Endurance runs: easy running to build a base, particularly early in the season.
• Strength and mobility: basic gym or bodyweight work to support the legs and trunk.

More background on how 400m and 800m training fits together is in the guide to 400m and 800m training basics. Always warm up thoroughly with jogging, dynamic stretching and a few build-up strides, and stop if you feel pain. New runners with health concerns should check with a doctor first.

Race-day routine

Arrive early enough to walk the track, find the call room and check your lane. Warm up so you finish about ten to fifteen minutes before the start: easy jogging, leg swings, skipping drills and three or four accelerations of 60 to 80 metres. Eat lightly and sip water rather than drinking a large amount just before the gun. Decide your plan before you step onto the track, for example “controlled first 200, tall on the back straight, drive at the line”, and repeat it to yourself on the start line. A single clear plan is easier to follow than five loose ones.

After the race

Walk or jog easily for several minutes and hydrate. A 400m is intense and the legs often feel heavy and stiff afterwards, which is normal. Record the splits you took at 200m so that you can compare race to race.

Frequently asked questions

Is the 400m a sprint or a middle-distance event?

Officially it is a sprint, but it demands endurance as well as speed. Many athletes come to it from both the 200m and the 800m.

What is a good 400m time for a beginner?

It varies widely by age, sex and training. Compare yourself with your own previous times and with local age-group results rather than elite marks.

Should I start in blocks?

Blocks help a fast start, but they require technique. If you are new, practise with a coach before using them in a race.
