Accuracy Notes
Every Half Marathon Pace Calculator on CalcIntel uses a documented formula. Results are estimates, real outcomes depend on assumptions and market conditions not captured in a simplified calculation.
Formula
Pace (min/mile) = total minutes ÷ miles. Speed (mph) = miles ÷ hours. To convert: 6:00/mile = 10.0 mph; 5:00/km = 12.0 km/h.
Worked Example
26.2 mi in 4:00:00
- distance
- 26.2
- time
- 4:00:00
- Result
- 9:09 / mile
240 min / 26.2 mi = 9.16 min/mi = 9:09 pace.

- Compare results across events, distances, or competitors.
Limitations & Common Mistakes
- Results are estimates, real-world outcomes depend on factors not captured in a simplified calculation.
