Garmin Forerunner 255S Smaller GPS Running Smartwatch - Advanced

Our review of the Garmin Forerunner 255S finds it is a solid choice for runners who want a compact watch that still delivers detailed training data and long battery life. The renewed Powder Gray model here targets athletes who prefer a smaller case without sacrificing GPS accuracy or recovery metrics. In this review the biggest reason to buy is that it balances a lighter, smaller fit with the same core running features found on larger models, making it easier to wear throughout the day and during sleep while still tracking workouts reliably.

Key Features

• Smaller GPS case: The reduced size offers a more comfortable fit for smaller wrists while keeping GPS tracking accurate for runs and outdoor activity.
• Advanced insights: Provides recovery, training load, and performance metrics so runners can plan workouts and monitor progress with meaningful data.
• Long-lasting battery: Extended battery life reduces charge interruptions so the watch can keep up through multi-day training blocks and regular use.
• Lightweight design: Powder Gray renewed finish and low weight make it unobtrusive during both workouts and daily wear.
• Run-focused features: Built to prioritize running metrics and GPS navigation, making it a focused tool for serious recreational and competitive runners.

Who It's For

The Forerunner 255S is best for runners with smaller wrists who still want advanced training metrics and reliable GPS without the bulk of larger sport watches. It suits training runners who value recovery insights, easy daily wear, and long battery life so they can track runs, sleep, and recovery without frequent charging.

Serious multisport athletes who need a larger screen for detailed navigation or those who want the absolute latest flagship features may prefer a different, larger model; likewise users seeking a fashion-forward everyday smartwatch rather than a focused running device should look elsewhere.
