Garmin Forerunner 945 Smartwatch


See available watches


For race days, training days and all the days between. Garmin’s newest Forerunner combines smartwatch functionality with advanced training tools. In a Forerunner first, the 945 looks at more than how you train but also where you train. Environmental details like elevation and temperature are now factored into your performance data. Speed, distance, pace and more come care of a new, more efficient GPS, along with other internal sensors. Using the latest generation Elevate heart rate monitor lets the 945 read your pulse straight off your wrist, no need for a chest strap. When you need more information, or even a little motivation, you can download training plans through the free Garmin Connect app. When paired with a smartphone running Garmin Connect your 945 goes from a training tool, to an everyday tool. Garmin Connect lets you review activities, receive texts, social media alerts, emails, etc., keep an eye on the weather and more. Get your training a soundtrack through popular music services and store up to 1000 songs. Detailed internal maps help you get where you need to go and if you don't have a course in mind, enter your desired distance and the 945 uses maps and tracks from other Garmin users to calculate options that start and stop right where you are.
