Running

Optimize every stride.

Calling all runners. Apple Watch Ultra 3 has everything you need to train smarter and reach your personal best. Powerful features like precision dual-frequency GPS, advanced metrics, Custom Workouts, and new Workout Buddy help you ace your pace. And now when you’re out on a run with just your Ultra 3, you can rely on speedy 5G.

The best GPS in a sports watch

A battery built for stamina.

Apple Watch Ultra 3 is engineered to give you even longer battery life — so you can go farther and wider than ever before. When you do need to power up, you can fast-charge in just 15 minutes for up to 12 hours of normal use.

Get help with Emergency SOS via satellite.

With a few simple taps, Ultra 3 can gather critical information, connect you to a satellite, and reach out to emergency services, so you can get the assistance you need as quickly as possible.

Stay connected with Messages.

Use Messages via satellite to stay in touch wherever you are. You can also send and receive texts, emoji, and Tapbacks via iMessage or use SMS.¹

Be found with Find My

Use Find My to share your location via satellite so friends and family know where you are. Before you go off grid, add the contacts you plan to share your location with using your paired iPhone or Ultra 3.

Find your Power Zones.

Connect your personal power meter to Ultra 3 to estimate your Functional Threshold Power (FTP), the highest level of intensity theoretically maintainable for an hour. Your FTP enables Power Zones to show your current power, time in a zone, and average power.

Watch your cycling metrics on your iPhone.

When you start a cycling workout on Ultra 3, it automatically shows up as a Live Activity on your iPhone — making it easier to see and safer when it’s mounted on your handlebars.

Crank it up with Workout Views.

Want to check your current speed as you ride? Workout Views put your chosen metrics front and center so they’re easy to track. And it’s simple to switch between metrics like Heart Rate Zones, splits, and elevation by turning the Digital Crown.

Master the Multisport workout.

Ultra 3 can recognize when you transition between swimming, cycling, and running — and record your metrics for each. Tracking your segments for a triathlon has never been easier.

Make a splash with swim stroke.

When you’re in a pool, Ultra 3 automatically detects your swim stroke, calculates auto sets with distance and pace, and provides advanced metrics like SWOLF to measure efficiency.

Know what’s Up Next.

For any Custom Workout you create, the Up Next view allows you to see what’s remaining in your current interval and what you’ll be tackling next. Pro moves.

Retrace your steps with Backtrack.

To get back on route, Backtrack uses GPS data to automatically create a path of where you’ve been when you’re off grid. You can easily add waypoints for locations, like trailheads or campsites.

Blaze a trail with custom routes.

Create and save custom walking and hiking routes on your iPhone. Choose from different route options: One way, out and back, or a loop — even get turn-by-turn directions — right from your wrist.

Aim higher with a Hiking workout.

Ultra 3 has a Hiking workout that lets you track your pace, distance, elevation gain, and calories burned. See how high you’ve climbed in real time, and get your total elevation gain when you’re finished. Sky’s the limit.

Download offline maps.

Plan ahead and download a map of where you’ll be hiking on your iPhone. It will automatically sync to your watch, so you’ll know where to go, even when you don’t.

Create waypoints in the Compass app.

Mark your current location or drop one on a trailhead or campsite. Cellular and emergency call waypoints automatically mark your most recent location within your available networks.

Go deeper with full dive capabilities.

Designed with Huish Outdoors, the Oceanic+ app turns Ultra 3 into a fully capable dive computer running a Bühlmann decompression algorithm. Turn the Digital Crown to get useful data at a glance. Equipped with all the safety warnings you’d expect, the app constantly calculates and monitors your dive parameters.

Get the Oceanic+ app

Let the Tides app guide you.

Get seven days of estimated information including rising, falling, high, and low tides, sunrise, and sunset. Check conditions at shorelines around the world, or search over 115,000 beaches by name.

Emergency SOS. ASAP.

For urgent help, press and hold the side button on your Ultra 3 to try to call emergency services and share your location. Don’t have cell service or Wi-Fi? Now you can text emergency services via satellite for vital assistance.

Fall Detection at the ready

If Ultra 3 detects that you’ve taken a hard fall, it can automatically help connect you with emergency services, provide dispatchers with your location, and notify loved ones.

Crash Detection. Your guardian on the go.

If you’ve been in a severe car crash, Ultra 3 can automatically help call emergency services, share your location, and notify your emergency contacts.

When you’re out, Check In.

Your watch can automatically notify someone when you arrive at your destination. And if you’re going for a run after dark, you can start a Check In for the duration of your workout to let your friend know when you’re done.

Activate a siren.

If you need to attract attention when you’re lost or injured, hold down the Action button to activate a siren that can be heard up to 600 feet or 180 meters away.

Let there be flashlight.

Illuminate nearby objects, alert others when you’re running at night, or shine a light in a campsite. You can also customize the Action button to control it

Set up your Medical ID.

In an emergency, first responders are able to quickly access critical medical information — like allergies or medications — directly from your Ultra 3.

Get notified of chronic high blood pressure.

Hypertension, or high blood pressure, impacts over 1.3 billion adults worldwide and is a leading cause of a heart attack, stroke, and kidney disease. The condition frequently goes undiagnosed because it often has no symptoms — and even during a doctor’s visit, with a single measurement it can be easily missed.

Receive hypertension notifications just by wearing your watch

Ultra 3 can notify you if it identifies patterns of hypertension. How? The optical sensor provides data to an algorithm that can detect potential hypertension by analyzing how your blood vessels respond to beats of the heart over 30‑day periods.

Groundbreaking insights. Grounded in science

We developed hypertension notifications using advanced machine learning methods and a series of studies totaling over 100,000 participants. The feature was then validated in a clinical study.

Set up a blood pressure log

If you receive a hypertension notification and have access to a blood pressure cuff, you can track your blood pressure in the Health app on iPhone to create a report that will lead to more meaningful conversations with your healthcare provider.
