Enter your distance and target time to see your pace breakdown.
How to Use This Tool
Enter your target race or training distance and your goal time. Select the distance unit (kilometers or miles) and your preferred pace unit. Click "Calculate Pace" to see a detailed breakdown of your splits, speed, and estimated effort.
Formula and Logic
The calculator converts your distance to kilometers if needed, then divides your total time by the distance to get pace per kilometer. It then converts to other units (miles, km/h, mph) for a full picture. Heart rate is a rough estimate based on speed.
Practical Notes

- Consult a doctor: Before starting a new training program, especially if you have health conditions.
- Training periodization: Use this tool to plan base, build, and peak phases in your training cycle.
- Dietary guidelines: Pair your running plan with adequate nutrition and hydration for best results.
