5K Pace Calculator
Calculate your 5K pace, finish time, or race splits. Enter goal time or current pace to see min/mile and min/km. Includes 5K time benchmarks by age and level.
The 5K (5 kilometres / 3.1 miles) is the most popular race distance in the world — and the most searchable. Whether you're targeting a sub-25 minute personal best or just finishing your first Parkrun, this calculator tells you exactly what pace you need to hold.
5K Pace Calculator: The Formula
Pace (min/km) = Finish time (minutes) ÷ 5
Pace (min/mile) = Finish time (minutes) ÷ 3.107
Example — targeting a 25:00 5K:
- Pace per km: 25 ÷ 5 = 5:00 min/km
- Pace per mile: 25 ÷ 3.107 = 8:03 min/mile
To find finish time from pace:
Finish time = Pace (min/km) × 5
Finish time = Pace (min/mile) × 3.107

Mile-by-Mile Splits for Popular 5K Goal Times
| Goal time | Mile 1 | Mile 2 | Mile 3 | Last 0.1 mile |
|---|---|---|---|---|
| 20:00 | 6:26 | 6:26 | 6:26 | 0:38 |
| 25:00 | 8:03 | 8:03 | 8:03 | 0:48 |
| 30:00 | 9:40 | 9:40 | 9:40 | 0:58 |
| 35:00 | 11:16 | 11:16 | 11:16 | 1:07 |
| 40:00 | 12:52 | 12:52 | 12:52 | 1:17 |
Print this and know your splits before the start. Many runners go out too fast in mile 1 and pay for it in miles 2–3.
Training to Improve Your 5K Time
Easy runs (Zone 2): 80% of your weekly mileage should be at a conversational pace — around 60–75 seconds per km slower than your 5K race pace. This builds aerobic base without accumulated fatigue.
Threshold intervals: 3–5 × 1km at 5K race pace with 90-second recovery jogs. Builds speed endurance specifically for the 5K distance.
Speed intervals: 6–10 × 400m at 10–15 seconds per km faster than race pace with 90-second recovery. Develops leg turnover and VO2 Max.
Weekly mileage: For a sub-30 minute 5K, aim for 25–35km/week. For sub-25 minutes, 40–50km/week. For sub-20 minutes, 60–80km/week with structured coaching.
Frequently Asked Questions
What is a good 5K time for a beginner?
For most beginners, finishing a 5K in under 40 minutes (run-walking allowed) is a great first goal. Completing your first 5K without stopping, regardless of time, is an achievement. Parkrun (free weekly timed 5K in parks worldwide) is the perfect low-pressure way to race for the first time.
How do I convert pace between min/km and min/mile?
To convert min/km to min/mile: multiply by 1.60934. To convert min/mile to min/km: divide by 1.60934 (or multiply by 0.6214). A 5:00/km pace equals 5:00 × 1.609 = 8:03/mile.
What's a realistic 5K improvement timeline for a beginner?
With consistent 3–4 days per week training, most beginners improve their 5K time by 2–5 minutes over the first 3 months. Moving from 35 minutes to sub-30 minutes typically takes 8–16 weeks of structured training. Sub-25 minutes usually requires 6–12 months of regular running.
Should I run the 5K at even pace or start slow?
Research consistently shows that even-split or slightly negative-split racing (second half marginally faster than first) produces the best times. Starting too fast (positive split) causes glycogen depletion and lactic acid accumulation that significantly slows the back half. Aim to run miles 1–2 at goal pace and push the last mile if energy allows.
How does 5K performance predict marathon time?
A rough prediction: Marathon time ≈ 5K time × 9.0–9.5 (for moderately trained runners). A 25:00 5K runner might target a 3:45–3:58 marathon. The multiplier is lower (closer to 8.5) for highly trained runners with good marathon-specific conditioning.
