If you feel unsafe or if your watch senses that an incident occurred, it can send a message to your emergency contacts with your location information3.
Take safety seriously. This watch can automatically send your name and location to the Garmin IERCC, a 24/7 staffed professional emergency response coordination center4 that can contact and communicate with local emergency services.
Use LiveTrack to let friends and family follow your real-time location and even view your entire preplanned course. Rest assured that your loved ones know exactly where you’re running or riding.
Get midrace motivation with audio5 and text messages from your family and friends.
LIVE EVENT SHARING

DAILY SUGGESTED WORKOUTS
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.
These free adaptive training plans feature guidance from expert coaches that adapt to you and your goals. Workouts sync right to your watch.
SYNC TRAINING PLANS
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.
EXTENDED BATTERY LIFE
Get up to 2 weeks of battery life in smartwatch mode and up to 7 hours in GPS mode with music and LTE LiveTrack.
Whether you’re running the city streets or riding densely covered trails, Forerunner 945 LTE provides built-in mapping to help keep you on track.

Use ClimbPro ascent planner on downloaded courses to see real-time information on your current and upcoming climbs, including gradient, distance and elevation gain.
Follow a route or course with help from turn-by-turn directions, which let you know ahead of time when the next turn is coming.
Enter a distance you want to run or ride and get suggested courses that will bring you back to your starting point. Trendline™ popularity routing helps you find the best local paths.
