The Garmin Forerunner 25follow GPS runners watch has been reviewed by Tristan Haskins aka CardioCritic (formerly HeartRateMonitor UK)

The Forerunner 25 takes the popular Forerunner 15 and adds Smart Notifications and Bluetooth data download to compatible smartphones (Android and iPhone).

It comes in TWO sizes, small and large and with OPTIONAL chest strap heart rate sensor. Just like the F15 before it, the Forerunner 25 includes an built in accelerometer that provides running metrics (pace, distance etc) when running indoors.

This same technology is also used 24/7 to give activity tracking feedback.

An Alternative GPS Running Watch from Polar ….

If you are considering this Garmin Forerunner watch then we would invite you to read the review of the Polar M400. The Polar M400 is, in our opinion, the BEST GPS RUNNER’S watch on the market.

It has all the PERFORMANCE tracking features you would expect from a competent runner’s watch, plus, a wealth of Training Load and Training Benefit feedback to help you better understand the training effect of each session and the predicted time required before you are fully recovered.

It also features a reliable and well researched/accurate Fitness Test that can be conducted once or twice a month to keep track of your general fitness improvement (based on RR intervals and HRV) … Just like the Forerunner 25 it’s also an activity tracker, sleep monitor and it’s smartphone connected for incoming alerts … plus it supports DOZENS of sports profiles, not JUST running.

Top Alternatives

Next Model UP

If you are content with the functionality of this model then you may be pleased to know there is now a Forerunner 35.

This newer model has the same functionality as the FR25 with the convenience of wrist based heart rate and a more stylish design.

Next Model DOWN

The next model down would be the Forerunner 15. The 15 does NOT have any Bluetooth connectivity so no smart notifications and no data download to the Garmin Connect APP.
