Designed for any environment

Forerunner 745 is made to go where your sport takes you. It’s built to hold up to 200 sweaty runs, bumpy bike rides and long swims.

Durable yet wearable

Comfortable for training, racing and for everyday life, Forerunner 745 is our smallest and lightest full-featured running and triathlon smartwatch.

Put performance at the top of your list.

Daily workout suggestions

For training guidance that takes you and your fitness level into account, get daily run and ride recommendations based on your current training load and training status.

Training effect

See how your workouts influence the development of endurance, speed and power with aerobic and anaerobic training effect feedback.

Recovery time

After each workout, recovery time lets you know when you’ll be ready for another hard workout. It even accounts for training intensity and factors such as stress, daily activity and sleep.

Built-in sports apps

Get built-in activity profiles for running, cycling, triathlon, pool and open water swimming, track running and more. For races and brick workouts, switch sports with just one button press.

VO2 max

Train smarter with VO2 max, an indicator of how you can expect to perform. This metric even accounts for changes in performance that could be caused by heat or altitude.

Race predictor

This specialised tool takes into account your fitness level and training history to help you work toward your race goal and see the impact of training on your predicted finish time.

Performance condition

While you run, Forerunner 745 analyses pace, heart rate2 and heart rate variability for a real-time assessment of your current ability to perform.

Training load

This stat measures your exercise volume from the last 7 days and compares it to the optimal range for your fitness and recent training history.

Training status

This metric evaluates your recent exercise history and performance indicators to let you know if you’re training productively, peaking or overreaching.

Cycling power

Connect to a compatible Garmin power meter (sold separately) to work toward a more efficient ride with help from cycling dynamics, FTP and advanced training methods.

Wrist-based heart rate

Get hassle-free heart rate data2, including advanced heart rate alerts and other features, to help you get the most out of your workouts.

Running dynamics

When used with a compatible accessory3, Forerunner 745 measures crucial running metrics such as cadence, stride length, ground contact time and balance, and more.

Multi-gnss

Access multiple global navigation satellite systems (GPS, GLONASS and Galileo) to better track in more challenging environments than GPS alone.

Garmin coach

These free adaptive training plans feature guidance from expert coaches and adapt to you and your goals. Workouts sync right to your watch.
