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.

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.

RACE PREDICTOR

This specialized 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 analyzes 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.
