See how your workouts influence the development of endurance, speed and power with aerobic and anaerobic training effect feedback.
After each workout, the built-in recovery time advisor lets you know how long to rest before another big effort. It even accounts for all-day stress, sleep6 and daily activities outside of workouts.
BUILT-IN SPORTS APPS
Switch up your workouts with activity profiles for cycling, triathlon, pool and open-water swimming, track running and more. For races and brick workouts, switch sports with a single button press.
Use this built-in activity profile to measure your running distance more accurately around a 400-meter track.
A new intervals data page and automatic classification keeps track of your fast and slow time, then separates them for you. Open repeats mode offers intervals structure with lap button control.
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.
The PacePro feature helps keep you on pace with grade-adjusted guidance as you run a course.
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.
While you run, analyze pace, heart rate and heart rate variability for a real-time assessment of your current ability to perform.
TRAINING LOAD FOCUS
This stat shows how your training load breaks down by categories of intensity and if that breakdown is balanced, focused or lacking in one or more areas.
This metric evaluates your recent exercise history and performance indicators to let you know if you’re training productively, peaking or overreaching.
WRIST-BASED HEART RATE
Our latest generation sensor provides heart rate data6 and alerts if your heart rate stays high while you’re at rest. Gauge how hard your heart is working during activities, even underwater.
When used with a compatible accessory7, Forerunner 945 LTE measures crucial running metrics such as cadence, stride length, ground contact time and balance and more.
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.
