This GPS running watch may look simple but it’s packed with cool features to keep your health and training on track.

Plus, with over 25 built-in GPS and indoor sports apps, including running, cycling and strength training, you'll have everything you need to crush your goals.

A vibrant 1.2” colorful AMOLED display is bright and easy to see, even in the sun. And the battery lasts up to 11 days in smartwatch mode, so you can wear it all day and still have enough juice left for your workouts.

Smart notifications let you stay connected with your friends and get messages on the watch, while Garmin Pay™ contactless payments keep your wallet on your wrist in case you want to stop for a coffee post-run. And if you run into an emergency, safety and tracking features let you send your location to a friend for peace of mind.

So whether you’re signing up for your first race or want to take your running more seriously to beat your best time, the Garmin Forerunner 165 will be a game-changer.
