Forerunner 225 is Garmin’s first GPS running watch to measure heart rate at the wrist using Mio Heart Rate Technology. Forerunner 225 uses an optical sensor that shines light into your skin and then measures the amount of light returned. Because there are slight changes as blood pumps through your wrist, the sensor detects those changes and uses a sophisticated filtering process to determine your heart rate. A light seal on the back of the watch blocks out ambient light to help ensure proper heart rate detection. Its colorful graphic interface shows your heart rate zone and beats per minute at a glance. This is the same Mio heart rate technology that you’ll find in the likes of the Mio Fuse and the Mio Alpha 2, as well as the Adidas miCoach Smart Run and the TomTom Runner Cardio.
Built-in activity tracker records steps, calories and distance throughout the day. Plus, it will remind you to move if you’ve been sitting for more than an hour. The watch is waterproof to 50 metres and battery life should go a full month in watch mode with activity tracking, or seven hours in GPS mode with heart rate monitoring. Data is automatically uploaded to Garmin Connect via a paired smartphone.
Forerunner 225 will be available in 2nd quarter only in one colour choice with a price of $299.99 USD.
