# Build an endurance workout

Some sessions need one clear goal: a distance to cover, time to spend moving,
or room to keep the endpoint open. Use **Schedule Workout** to build a run,
ride, or swim, then add it to your calendar. You are planning the session
here, not recording it.

## Choose where the workout belongs

Use Momentum on an iPhone or iPad. Choose today or a future date inside an
active training plan. A paused plan cannot receive the workout.

## Set one goal for the session

### Open the builder

1. Open **Plan**.
2. Select the date.
3. Open **Add**.
4. Select **Schedule Workout**.
5. Choose the training plan if Momentum offers more than one.
6. Select the run, ride, or swim activity.

### Choose the location and goal

1. Choose **Indoor** or **Outdoor** for a run or ride, or **Pool** or **Open
   Water** for a swim.
2. Tap **Continue**.
3. Select an available goal:
   - **Open** leaves the endpoint open.
   - **Time** sets a duration.
   - **Distance** sets a distance.
   - **Energy** sets an energy goal.
4. Tap **Continue**.
5. For **Time**, **Distance**, or **Energy**, set the value shown.

For distance, check the unit alongside the number. If you want work and
recovery segments instead of one goal, choose **Intervals** and follow
[Build intervals](./build-intervals.md).

### Review and keep the workout

1. Tap **Review Workout**.
2. Check the receiving **Plan**.
3. Open **Schedule**.
4. Choose a one-time date or a repeating schedule.
5. Return to the workout review.
6. Tap **Add Run**, **Add Ride**, or **Add Swim**, matching the activity.

See [Schedule a workout once or repeatedly](../plan/schedule-workout.md) for
weekday, frequency, and ending choices.

## Find the plan on your calendar

After a successful addition, Momentum saves the schedule locally, closes the
review, and shows confirmation. Find the workout on its date in **Plan**.

**Review Workout** alone does not save the schedule. Adding the workout does
not start a session, record a result, or confirm delivery to Apple's Workout
app.

## Keep the goal and the result separate

A distance goal does not predict how long you will take. Any estimated
duration remains a planning estimate, not a time goal or a recorded result.
When you open an existing workout, use the goals it actually contains; a
duration estimate alone does not describe intervals or a distance target.

Available goals depend on the sport, location, and support in Apple's Workout app.
Choose an available goal for the location where you will train. **Open
Water** supports single-goal swims in this builder, not intervals.

If **Couldn't Add Workout** appears, follow its reason before trying again.
Reopen scheduling if the receiving plan changed, or shorten the schedule or
simplify the workout if it is too large.

Momentum does not live-track endurance workouts. A compatible workout's
delivery to Apple's Workout app is separate from this local planning task.

## Shape the next part

- [Build intervals](./build-intervals.md) to combine work, recovery, and repeats.
- [Schedule a workout once or repeatedly](../plan/schedule-workout.md) to choose its dates.
- [Planned and performed values](../concepts/planned-and-performed-values.md) explains goals, estimates, and results.
- [Sync and delivery](../concepts/sync-and-delivery.md) explains what a local save does and does not confirm.
