How does pace relate to speed?
Pace is the time needed to run one kilometer, and speed is the distance covered in one hour. The converter divides 3600 seconds by your pace to give the average speed, so 5:00 per kilometer equals exactly 12 km/h.
Which race times are projected?
The tool projects finish times for 5K, 10K, half marathon and full marathon by multiplying your pace by the official distance. These are linear estimates and do not account for hills, weather or fatigue during the race.
