Calculate pace, speed, time, or distance for any activity. Convert between units and get split times for common distances.
How long it takes to cover one unit of distance. Common in running and swimming.
How much distance covered in one unit of time. Common in cycling and driving.
Quick Conversion:
To convert pace to speed: Speed (mph) = 60 ÷ Pace (min/mile). To convert speed to pace: Pace (min/mile) = 60 ÷ Speed (mph).
| Pace (min/mile) | Pace (min/km) | Speed (mph) | Speed (km/h) | 5K Time | 10K Time | Marathon |
|---|---|---|---|---|---|---|
| 6:00 | 3:44 | 10.0 | 16.1 | 18:38 | 37:17 | 2:37:22 |
| 7:00 | 4:21 | 8.57 | 13.8 | 21:45 | 43:30 | 3:03:36 |
| 8:00 | 4:58 | 7.5 | 12.1 | 24:51 | 49:43 | 3:29:50 |

Use your current pace to predict finish times for different distances. A 5K pace typically predicts 10K pace within 10-15 seconds per mile slower.
Base your training paces on your current race pace or threshold pace. Different workouts require different pace zones.
Even pacing (same pace throughout) is most efficient for races. Negative splits (faster second half) indicate good pacing discipline.
Adjust pace for heat (+15-30 sec/mile), altitude (+10-20 sec/mile per 1000ft), wind (+5-15 sec/mile), and hills (variable).
Track pace improvements over time at the same effort level. A 10-15 second per mile improvement over 8-12 weeks indicates good training adaptation.
