Run free, no chest strap, no wallet, just you chasing your next PR. The latest generation Elevate optical heartrate monitor takes your pulse straight off your wrist. A GPS and an internal accelerometer handle speed and distance info, turning it into data that credits time in the gym and on the trails. When paired with the free Garmin Connect app on your phone, a whole new set of features open up. Review activities, receive notifications, control certain apps on your phone. Strava live segment integration (requires Strava premium) uses your phone to show you nearby segments as you run. On-the-fly integration means that you won't have to pre-load segments, though starred segments will still appear like you’re used to. Compete, share and learn with the 645 and Strava’s digital running community. Not just great for running, activity tracking, sleep monitoring and smart notifications make the 645 useful on rest days too.
