The Garmin Forerunner 45 is your no-frills GPS running watch. It tracks essential stats like heart rate, distance traveled, pace, cadence, and intervals, allowing you to accurately gauge your development and create training plans that work for you. The watch uses an optical heart rate monitor and GPS to track your metrics more accurately, and you’ll even have access to more advanced metrics like stress and energy levels and VO2 Max, which gives you more information about lung capacity and endurance. You’ll also get smartphone notifications like calls and texts, plus a brand new incident detection feature that will automatically call for help if the watch detects that you may have been involved in an accident while on a run. The Forerunner 45 comes with a silicone strap and a 42 mm watch case, and is waterproof up to 5 ATM. Battery life is about a week when just used as a smartwatch, and up to 13 hours with GPS continuously turned on — long enough to last you through an ultra marathon!
