Show Description

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. The 945 can even give your training a soundtrack, with the ability to connect to multiple music services and storage for up to 1000 songs. With tunes and podcasts on your wrist, you can cut weight by leaving your phone at home. Loaded with detailed internal maps, the 945 can help you get where you need to go. And, for those times you know how far you want to go, but don't have a course in mind, the 945 can help. Enter your desired distance and the 945 will use its maps and tracks from other Garmin users to calculate multiple course options that start and stop right were you are.
