A bestseller that continues to evolve and adapt to the needs of the most demanding multisport athletes: the new Garmin Forerunner 255 is here. A fantastic new smart watch with integrated GPS which comes with features for runners accustomed to training hard. The Forerunner 255 also now has optimised features for triathletes.

The Garmin Forerunner 255 GPS sports watch comes with enhancements such as more advanced metrics and training functions, smart notifications, and smartwatch features (when connected to a compatible smartphone).

A standout aspect of the Garmin Forerunner 255 is its availability in two sizes, with cases measuring 41mm and 46mm, ensuring a perfect design and fit for daily activities and continuous wear.

This model introduces a multiband and multi-satellite GPS system, incorporating the most popular navigation systems currently available: GPS, Galileo, and GLONASS. This enhancement significantly improves accuracy in measuring training parameters, helping athletes gauge their speed and distance more effectively.

How can you adapt the Garmin Forerunner 255 to your daily workouts?

Adapting the Garmin Forerunner 255 to your daily workouts is straightforward. It provides comprehensive insights into your workouts and recovery, monitoring your performance closely. New features include daily training recommendations through the updated running widget.

The morning report widget is a notable addition, offering a daily summary and, when synced with your smartphone, provides training suggestions, sleep quality assessments, and more. It also includes specific metrics such as heart rate variability to better monitor recovery and overall well-being, with customizable reports to show only the metrics you choose.

The Garmin Forerunner 255 aims to give athletes a deeper understanding of their physical condition, helping assess the productivity of their training sessions and the risk of overtraining.

Race day planning and preparation

With the new race widget, runners can now include a performance prediction for race day, initiate a countdown, and even check the weather.

Similar to most GPS heart rate monitors and sports watches in the Forerunner line, the latest F255 version connects to the Garmin Coach platform. This allows runners to set up personalized training plans for specific distances such as 5k, 10k, and 21k. These complimentary plans are customized to the runner's goals and performance levels.

Performance metrics are readily available for runners who seek them, via the exclusive Garmin Firstbeat Analytics feature. This includes VO2 max, maximum effort, performance condition, and training status among others. The PacePro feature offers guidance on pacing, while the Trendline feature suggests the best local routes, and allows for the creation of new ones in Komoot and Strava. The exclusive Running Power function provides metrics on the power exerted in each stride.

Designed for triathletes

A major highlight of the new Forerunner 255 is its design, optimized by Garmin product developers for triathlon enthusiasts. It allows for quick and easy switching between different sport profiles during training or competition, with just the click of a button.

Additionally, connecting the watch with the Running Dynamics Pod or HRM-Pro add-ons enhances its features with running power measurement. This enables tracking of running dynamics, including stride length, cadence, ground contact time, and more.

Garmin Forerunner 255 Health and Wellness Tracking

The Garmin Forerunner 255 is also designed to track overall wellness 24/7 with the following functions:

  • Pulse OX3: wrist pulse to monitor blood oxygen saturation levels.
  • Body Battery: displays current energy levels to help athletes find the best times for activity and rest.
