Frequently Asked Questions
How do I calculate my running pace?
To calculate your running pace, select "Calculate Pace" mode, enter your distance (in km or miles), enter your time (hours, minutes, seconds), and click Calculate. The tool will show your pace in min/km and min/mile, plus your speed in km/h and mph.
What is a good 5K pace?
A good 5K pace varies by fitness level. For recreational runners, 6-8 min/km (10-13 min/mile) is common. Intermediate runners often achieve 5-6 min/km (8-10 min/mile), while competitive runners can maintain under 4 min/km (6.5 min/mile). The calculator helps you track your progress.
How do I use the split times feature?
Split times are automatically calculated when you compute your pace. They show how long it would take to complete standard race distances (1K, 5K, 10K, 15K, 10 miles, half marathon, marathon) at your current pace. This helps with race planning and goal setting.
Can I calculate distance from pace and time?
Yes! Select "Calculate Distance" mode, enter your target pace (min/km or min/mile), enter how long you plan to run, and click Calculate. The tool will show the distance you can cover at that pace.
How do I calculate my marathon finish time?
Select "Calculate Time" mode, enter 42.2 km (or 26.2 miles) as the distance, enter your target pace per km/mile, and click Calculate. The tool will show your estimated marathon finish time and split times for every standard distance.
What is the difference between pace and speed?
Pace is time per unit distance (min/km or min/mile) - commonly used by runners. Speed is distance per unit time (km/h or mph) - commonly used by cyclists. Our calculator shows both so you can use whichever metric you prefer.
