Track Your Health

The Forerunner 945 has multiple methods of keeping tabs on your health and how your workouts benefit you. It tracks VO2 max, allowing for heat and altitude adjustments, helping you determine your aerobic endurance. You also get feedback on the aerobic and anaerobic benefits of your training.

Your heart rate is also tracked via a built-in wrist sensor, and a Pulse Ox wrist sensor monitors your blood oxygen saturation. The essential readings work on building up your ability to handle high endurance activities. Finally, training load and recovery time, which are designed to give you feedback on the volume of your exercise, tell you when you'll likely be ready to exercise again. To determine your training load, the Forerunner compares the last 7 days of activity against the optimal range for your fitness and recent training history.

HRM-TRI & HRM-Swim Included

The HRM-Tri and HRM-Swim are included wearable monitors that are designed to give you detailed heart rate data when running or swimming. This data can then be forwarded to your Forerunner 945 when finished. With the HRM-Tri, you can get additional running metrics when using it in conjunction with the Forerunner 945.

HRM-Tri: The adjustable strap and lightweight monitor are designed to be comfortable during workouts. The additional running metrics gained when using this with the Forerunner are cadence, stride length, ground contact time, ground contact time balance, vertical oscillation, and vertical ratio.
HRM-Swim: This strap and lightweight sensor are specifically designed for swimmers. It's designed to be non-slip and stable, even during wall push-offs.

Garmin Coach

Supporting Garmin Connect, this sports smartwatch allows you to download and sync free workouts and adaptive training plans right to the watch. The plans feature guidance from expert coaches and adapt themselves to your specific goals. They are ideal ways to add variety to your training regime.

Activity Profiles

Built-in profiles let you switch up your exercises with support for indoor and outdoor running, indoor and outdoor cycling, pool or open water swimming, cross-country skiing, paddle sports, trail or treadmill running, and much more. With the push of a button, you can quickly switch between exercises, which are ideal for du/triathlon training.

Body Battery

The Forerunner 945 collects data to give you a Body Battery measurement, which gauges how much energy you're likely to have at a given moment.

Sleep and Stress Tracking

In addition to all-day stress tracking, the Forerunner 945 will monitor your sleep. It monitors your total sleep and any periods of movement or restful sleep.

Full-Color Mapping

When utilizing the built-in GPS, GLONASS, and Galileo tracking abilities of the Forerunner 945, you can conveniently view your position on the watch with full-color maps. There's also the Trendline feature that compares your location with the billions of miles of Garmin Connect data to find the best trails and routes.

Stay Connected

Pair the Forerunner 945 with your smartphone and you'll gain the ability to stay connected with the outside world while working out. Receive text messages, social media updates, emails, and more right on your wrist.

Garmin Pay

With support for Garmin Pay, you can workout light by leaving your wallet at home or in the car but still have the ability to make purchases; just tap the Forerunner 945 to a Garmin Pay-compatible reader at participating locations: a convenient way to grab an extra water or post-run snack.

Safety Tracking

When paired with your smartphone, you can use the safety-tracking feature to share your location with specific contacts. If you are lost, hurt, or otherwise in need of help, you can use this feature to manually contact someone. There is also built-in incident detection that can contact someone for you automatically when triggered.
