The Garmin Forerunner 225 has an always-on display, accurate GPS for tracking your runs, a wrist-based heart-rate monitor and is able to track steps made and amount of calories you have burnt. Above all, it is water-resistant and can be worn in the shower and pool. However, this watch lacks automatic syncing, sleep data doesn’t have detailed information and has limited workouts.

This is the first Garmin running watch to have heart rate tracking from the wrist. It now joins the league of TomTom, Adidas and Microsoft which has all in one BPM tracking from a single device. This watch has some drawbacks like lack of USB charging, a bit bulky and lacks a few high-end features.


With the Garmin Forerunner 225 review, we realise a big and bulky but attractive smartwatch. The watch measures 48mm across compared to Apple Watch which measures just 42 mm. it is available in a single color of black and red accents. In addition, the Garmin Forerunner 225 has a water resistance of 50 meters and it is bright enough hence no need of tapping. It also has a backlight in case you are unable to see clearly.

The Garmin Forerunner 225 is almost similar to the Garmin 620 and the Garmin 220. It has a soft silicon strap that makes it comfortable wearing for longer periods. It is round in shape with side button controls. It weighs about 54g which is a better weight when we compare it to the Polar V800 that weighs 81g. It is more compact when we compare it to other Optical Heart Rate (OHR) sensor watches like the TomTom Cardio Runner and the Adidas SmartRun.

It also features a colour LCD display which is sharp and easy to read while doing your activities.


When we review Garmin Forerunner 225, it has an optical heart rate sensor with the same technology found in the Fitbit Surge as well as the Apple Watch. It is designed in such a way that it has a flickering LED green light which basically lights up the capillaries for the sensor to measure the blood as it flows in the body. The heart rate in Garmin 225 however is not effective as seen in Fitbit Charge HR whereby kit runs continuously the entire day.

It also features a GPS which is responds quickly as it acquires the signal within a couple of seconds in all conditions.

Activity Tracking

The watch also has two workout screens having three customizable lines. The third screen is designed to display your heart rate whereas the fourth one is meant to display time and data. It offers an array of 14 data points the user can choose from. They include timer, lap time, heart-rate, average heart-rate, calories, distance, pace, average pace, lap space, speed, distance, cadence, HR zones and elevation.

It also has a color gauge that displays the heart rate training zone the user is in while working out. The gray color shows that you are in the warm-up zone, blue is easy zone, green is the aerobic, orange the threshold whereas red is the maximum zone. It also the Auto pause that automatically pauses when you stop, the auto lap that automatically record lap data and the interval training that is for creating custom workouts.


When it comes to connectivity reviews of Garmin Forerunner 225, the watch is able to sync wirelessly, syncs automatically and has Bluetooth.


According to Garmin Forerunner 225 reviewed battery features, it can take up to 10 hours with an active GPS signal and the optical heart-rate sensor on. It will take you approximately four weeks when you are using it as an activity tracker.


It essentially depends on the type of watch you want and for what purpose you want to use. An ordinary basic activity tracker will find a Fitbit Charge, Jawbone Up2 or Garmin Vivofit 2 useful. There are runners who don’t prefer heart-rate and activity tracking in their GPS watches. The Forerunner 220 might be important for them otherwise the Garmin Forerunner 225 is suitable for runners who want accurate GPS running watch capable of measuring heart rate and all-day outdoor activity tracking.
