Release Date (UK) > August 2015

Product it replaced > Garmin Forerunner 210

Suggested Retail Price (when new) > £149

Replaced by > Still a valid product but a better option could be the Forerunner 35 (Oct 2016) with wrist based HR


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.

Confused by How Many Forerunners there are?

You are not alone. If you are thinking of getting a Garmin GPS running then you will be joining a club of thousands. There have been over 15 models in the Forerunner range so we published this guide to the Garmin Forerunner which compares the main differences between all the models from the original Forerunner 101 in 2003 to the latest products.

Highly Effective GPS Running Watch

This compact yet competent running watch has 95% of the features that 95% of runners will probably ever need. The latest technology makes uploading your training history a doddle. At the end of the of the day everything can be manually downloaded to PC / Mac via supplied USB cable or auto-synced to your smartphone via Bluetooth and the Garmin Connect APP.

Next Model Up

If you are looking at the next model up then you are probably looking at shifting up from “fun runner” to “competitive runner”. If that’s the case we’d recommend either the Forerunner 230 or Forerunner 235 with off the wrist hear rate technology. However, 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.

Closest alternative Running watches?

If you are predominantly a runner looking for a sports watch with Heart Rate & GPS there are some competent alternatives from Polar.

Video Presentation

If you want to improve your running times then you need help getting there. A GPS running watch with proper features designed to make you run at a steadier pace is a way of taking the next step to becoming a better runner. The Garmin Forerunner 25 is an easy-to-use GPS watch that tracks how far, how fast and how long you’ve been running. It has an optional heart rate sensor to monitor your training effort.  This short video from Garmin gives a nice “hands-on” view of this great sports watch. We hope to add our own video review shortly.

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.
