# Marathon Pace Calculator

Free marathon pace calculator. Convert your marathon time to min/km or min/mile and get VDOT-style training paces for easy, tempo, threshold, and interval runs.

Use your marathon time (or a recent shorter race) to set training paces and build a simple pacing strategy for race day.

- Marathon pace in min/km and min/mile
- Training zones that match your fitness
- Pairs well with course elevation + fueling planning

## How to calculate your marathon pace and training zones

Enter your marathon time to calculate goal pace and supporting training paces for workouts.

1. Choose marathon distance: Set distance to 42.195 km (26.2 miles).
2. Enter your time: Use a recent marathon or a realistic goal time.
3. Use zones in training: Build volume with easy runs and add tempo/threshold workouts.

## Frequently asked questions

### How do I pace a marathon evenly?

Start slightly conservative, settle into goal effort, and avoid surges early. If the course is hilly, adjust effort (not pace) on climbs.

### Can a 10K or half marathon predict marathon pace?

Yes. Shorter races are useful predictors, especially when combined with consistent long-run training.
