If you're in the United States, your Apple Watch may recognise when you've arrived at a standard-shaped outdoor track with visible lane markings with Automatic Track Detection.1 When you start an Outdoor Run, you'll be prompted to select the lane in which you plan to run. Automatic Track Detection uses both GPS and Apple Maps data to try to give you the most accurate distance, pace and route map. You can also add an alert for each lap completed during a track run in the Alerts settings of the Workout app.
To see your progress, check your watch face. Pace alerts are available for Outdoor Run only.
If you have Apple Watch Ultra, you can set your running workout to the Action button. You can also turn on Precision Start in workout settings, which will show when you have a GPS signal and will skip the countdown automatically.

Running form metrics
There are a number of metrics to help you get the most out of your running workout.2
Vertical Oscillation: Tap to add an estimate of how much your body travels vertically as you run, measured in centimetres. This measurement, along with stride length, can give you a sense of how much energy you're using to drive upwards versus forwards. Apple Watch can log your vertical oscillation automatically during outdoor running workouts.
Running Stride Length: Tap to add an estimate of how much distance you cover from one step to the next while running, measured in metres. Along with cadence, stride length determines your overall running speed. Apple Watch can log your running stride length automatically during outdoor running workouts. For the best Stride Length estimates, run for approximately 200 metres to calibrate your Apple Watch.
Ground Contact Time: Tap to add an estimate of the time each foot spends touching the ground while running, measured in milliseconds. Apple Watch can log your ground contact time automatically during outdoor running workouts.
Heart Rate Zones: Tap Include to add Heart Rate Zones to get a sense of your intensity level.
Running Power: Tap Include to show an estimate of the work you're doing while running, measured in watts. Running Power reflects the intensity of your run and can give a sense of your effort as your speed or incline changes. Apple Watch can log your Running Power automatically during outdoor running workouts. Running Power is only reported during running workouts and cannot capture any extra load, such as a weighted backpack.
Elevation: Tap Include to show your elevation while you're running.
Activity Rings: Tap Include to show the progress of your Activity Rings during your workout.
