You ran 10K in 50:00 — that's 5:00 per km.
Choose pace, time or distance — the other two become the inputs.
Type the distance, time or pace you already know. Switch between km and miles freely.

Rough guide based on amateur athletes worldwide. Pace varies with terrain, weather and training, so treat these as orientation, not a verdict.
| Beginner | 6:30 – 7:30 min/km | New to running, building base mileage. |
| Intermediate | 5:00 – 6:30 min/km | Trains 3–5 days a week, has finished a 10K. |
| Advanced amateur | 4:00 – 5:00 min/km | Sub-1:30 half marathon, structured training. |
| Elite amateur | < 4:00 min/km | Sub-3 marathon territory or faster. |

Pace is total time divided by distance. For example, running 10 km in 50 minutes is a pace of 5:00 min/km. This calculator does the math instantly and converts between min/km and min/mi.
Most beginners run between 6:30 and 7:30 min/km (about 10:30–12:00 min/mi) on flat terrain. Conversational pace — where you can still hold a chat — is a healthier guide than chasing a specific number.
A 4-hour marathon is roughly 5:41 min/km. Sub-3:30 means about 4:58 min/km, sub-3:00 means 4:16 min/km, and elite amateurs typically run under 4:00 min/km. Use the predictor above to plan yours.
Predictions assume even pacing and similar terrain. In practice, marathon time is rarely exactly twice the half — fatigue, fueling and the course profile all matter. Treat predictions as a starting point and refine with race results.
Most weekly mileage should be slower than race pace. Race-pace work belongs in tempo runs, intervals and race-specific long runs. The pace calculator helps you set those targets without overthinking the math.
