Our Take
The Garmin Forerunner 255 is a GPS running watch aimed at dedicated recreational runners and those training for events who want serious performance data without stepping up to the more expensive Forerunner 955 or Fenix range. It sits firmly in the mid-market, offering a strong feature set for the price and representing one of Garmin's most balanced all-round running watches.
Key Features
Built-in multi-band GPS for improved positional accuracy in urban environments and tree cover
Running dynamics metrics including cadence, stride length, and ground contact time
Training readiness and recovery time suggestions based on sleep and HRV data
Up to approximately 14 days battery life in smartwatch mode, around 30 hours in GPS mode
Garmin Coach integration for structured training plans delivered directly to the watch
Compatible with Garmin Pay contactless payments (on the 255 Music variant)
Our Verdict
A strong buy for runners who train consistently and want meaningful data to guide their sessions. The battery life and training tools make it particularly good value at its price. Casual joggers will find it more than they need, and those wanting maps or a polished smartwatch experience should look at pricier alternatives.
