Garmin Forerunner 255S GPS Running Watch AW22

Garmin Forerunner 255 GPS Running Watch

A streamlined, lightweight watch, Garmin’s Forerunner 255S GPS Running Watch is the smaller version of the Forerunner 255S, great for smaller athletes.

Morning Report

When you wake up in the morning you’ll receive your Morning Report, which provides an overview of sleep, recovery, and training outlook, alongside HRV status, and weather. You can customise the Morning Report to show you exactly what you want to see.

HRV Status

Delivering a deeper understanding of your overall health, your recovery, and training performance, HRV Status provides analysis through heart rate variability while you sleep – based on technology by Garmin’s Firstbeat Analytics™ team.

Built-In Sports Apps

Perfect for when you want to change things up, Garmin’s Forerunner 255S GPS Running Watch includes 30+ built-in activities, including triathlon and open-water swimming profiles.

Race Widget

Prepare for race day with Garmin’s Race Widget, which provides training tips, personalised daily suggested workouts, and completion time predictions based on course details, weather, and performance.

Daily Suggested Workouts

View your entire week of daily suggested workouts, which adapt after every run to match your performance and recovery as well as the races coming up in your Garmin Connect™ smartphone app calendar.

Garmin Coach

With the Forerunner 255S you’ll receive free adaptive training plans, including 5K, 10K, and half-marathon programmes, featuring guidance from expert coaches that adapt to you and your goals.

Multi-Band GNSS Support

With the Forerunner 255 you can access multiple global navigation satellite systems, and get access to multiple frequencies sent by navigation satellites for improved accuracy in areas where GNSS signals are reflected, weak, or typically don’t penetrate – ensuring superior accuracy for tracking how far and how fast you run, even in the most challenging of environments.

Garmin Pay Contactless Payments

Run without fear of leaving your wallet at home with Garmin Pay, Garmin’s contactless payment system that lets you make payments straight from your watch face, through participating providers.
