## How Half Marathon Pace Is Calculated

A half marathon is 13.1 miles (21.0975 km).

### Formula

**Pace (min/mile) = Total Time (minutes) / 13.1**

### Training Notes

Your half marathon pace is typically 15-30 seconds per mile slower than your 10K pace. A proper training plan should include tempo runs at or near half marathon pace.

Exemple Résolu

You want to finish a half marathon in 2 hours.

  1. Total time = 2 * 60 + 0 = 120 minutes
  2. Pace = 120 / 13.1 = 9.16 min/mile
  3. That is 9 minutes and 10 seconds per mile
  4. Speed = 13.1 / 2 = 6.55 mph
