## How the Run/Walk Method Works

The Galloway run/walk method alternates running and walking intervals throughout a race.

### Formula

**Effective Pace = (Run Fraction x Run Pace) + (Walk Fraction x Walk Pace)**

Where:
- **Run Fraction** = Run Interval / (Run Interval + Walk Interval)
- **Walk Fraction** = Walk Interval / (Run Interval + Walk Interval)

### Benefits

The run/walk method reduces injury risk, allows better recovery, and often produces faster finish times than running continuously at a slower pace.

计算示例

Running 4 minutes at 10:00/mile pace, walking 1 minute at 16:00/mile pace for a half marathon.

  1. Run fraction = 4 / (4 + 1) = 0.80
  2. Walk fraction = 1 / (4 + 1) = 0.20
  3. Effective pace = 0.80 * 10 + 0.20 * 16 = 8.0 + 3.2 = 11.20 min/mile
  4. Finish time = 11.20 * 13.1 = 146.7 minutes
  5. That is 2 hours 27 minutes
