Running benchmark
How Fast Should You Run One 400m Lap for Your Age?
One lap is long enough to test your engine and short enough to demand speed. Use it to measure pace, conditioning and recovery after 40.
There is something beautifully cruel about a 400m track. It looks harmless, but the lap sits in an uncomfortable middle: longer than a sprint, much faster than a steady run, and demanding both anaerobic power and aerobic conditioning.
Running speed also draws on coordination, tendon stiffness, balance, leg strength and breathing control. That makes a controlled hard lap a useful real-world test of whether you can still move with intent, rather than merely jog.
How to run the test
- Use a measured 400m athletics track where possible.
- Jog easily for 5–10 minutes, then do leg swings and several relaxed strides.
- Run one lap hard but controlled. Push without turning the final straight into a collapse in form.
- Record the time and how you felt. Do not repeat a maximal test if anything hurts.
400m run times by age
| Age | Strong | Solid / respectable | Needs work |
|---|---|---|---|
| 40–49 | Under 75 sec | 75–95 sec | Over 105 sec |
| 50–59 | Under 85 sec | 85–110 sec | Over 120 sec |
| 60–69 | Under 100 sec | 100–130 sec | Over 140 sec |
These are practical benchmarks rather than official athletics standards. The original bands leave a transition zone between the upper end of “solid” and the “needs work” cutoff; treat a time in that gap as below respectable, with room to improve.
The 400m recovery test
Run 400m hard but controlled, rest for two minutes, then run another 400m. Calculate how much slower the second lap was: second-lap time minus first-lap time, divided by first-lap time, multiplied by 100.
| Second lap | What it means |
|---|---|
| Within 5–10% | Good. You can run hard and back it up. |
| 10–15% slower | Normal for many men. Your conditioning is decent, with room to improve. |
| 15–20% slower | Your speed is probably ahead of your engine. You can go, but not yet sustain it. |
| More than 20% slower | You went out too hard, your conditioning needs work, or both. |
Your heart rate should begin dropping during the two-minute rest. If it barely moves or you still feel ruined before lap two, slow the first lap next time.
Recovery matters more with age. The goal is to run fast, regain control and repeat without your technique falling apart.
Six-week 400m progression
Do one session each week at roughly 7–8 out of 10 effort. Every rep should be fast enough to make you work while staying controlled. Your last rep should remain close to your first.
| Week | Beginner / returning | Intermediate | Strong runner |
|---|---|---|---|
| Week 1 | 6 × 100m relaxed fast; walk back | 6 × 200m; walk 200m | 4 × 300m; rest 2–3 min |
| Week 2 | 8 × 100m relaxed fast; walk back | 8 × 200m; walk 200m | 5 × 300m; rest 2–3 min |
| Week 3 | 6 × 150m; walk back | 4 × 300m; rest 2–3 min | 4 × 400m; rest 3 min |
| Week 4 | 6 × 200m; walk 200m | 5 × 300m; rest 2–3 min | 5 × 400m; rest 3 min |
| Week 5 | 4 × 300m; rest 3 min | 4 × 400m; rest 3 min | 6 × 400m; rest 3 min |
| Week 6 | Test: 1 × 400m controlled hard | Test: 400m, rest 2 min, repeat | Test: 2 × 400m; rest 2 min |
Start conservatively
If you have not run hard in years, start with the beginner column rather than attempting repeated 400s immediately. Add easy walking, riding or running around the weekly session, and leave enough recovery for your calves and Achilles tendons. Stop for chest pain, faintness or unusual breathlessness and seek medical advice.
One lap does not describe your entire fitness. It does answer three useful questions: can you still move fast, can you recover, and do you still have another gear?
