Frequently Asked Questions
How accurate is the pace calculator?
Our calculator provides highly accurate pace calculations based on standard running formulas. The heart rate zones and VO2 Max estimates are based on established physiological models used by professional coaches and sports scientists.
What's the difference between pace per mile and pace per kilometer?
Pace per mile is commonly used in the US, while pace per kilometer is used internationally. 1 mile = 1.60934 kilometers, so a 6:00/mile pace equals approximately 3:44/km pace.
How do I use the multipoint calculator?
Enter the distance and time for each segment of your run. The calculator will show your pace for each segment and help you analyze performance variations throughout your run.
What is VO2 Max and why is it important?
VO2 Max is the maximum amount of oxygen your body can use during exercise. It's a key indicator of cardiovascular fitness and endurance performance. Higher VO2 Max generally correlates with better running performance.
How can I improve my running pace?
Focus on consistent training, proper recovery, and varied workouts including easy runs, tempo runs, intervals, and long runs. Use the training zones to structure your workouts effectively.
