Garmin Forerunner 55 Training Features
An affordable GPS running watch for beginners. Tracks the basics but lacks advanced training intelligence features like Training Readiness and HRV Status.
Best For
New runners who want GPS tracking and basic training metrics without information overload. Great first serious running watch.
Our Verdict
The Forerunner 55 covers the essentials — GPS pace, VO2 Max, and Recovery Time — but skips the deeper recovery intelligence that experienced athletes rely on. If you are just starting to run consistently, it is more than enough. If you already train 4+ days per week and want data-driven recovery guidance, the Forerunner 165 or 265 is a better starting point.
Garmin Forerunner 55: In-Depth Review
The Forerunner 55 is Garmin's entry point into dedicated running watches, and it does that job well without overwhelming new runners with data they are not ready to use. The GPS is accurate for pace and distance, Body Battery gives a simple daily energy reading, and Recovery Time tells you when your body is ready for the next hard session. VO2 Max tracking lets you see aerobic fitness improving over weeks and months of consistent training.
Where the Forerunner 55 shows its age is in the metrics it cannot track. There is no HRV Status, which means you miss the autonomic nervous system trend data that more advanced watches use to flag overtraining early. There is no Training Readiness score, so you wake up without a single number telling you whether today should be hard or easy. And there is no Training Load tracking, meaning you cannot see whether your weekly volume is building, maintaining, or declining.
For a first-time runner building the habit of lacing up three times a week, none of those missing features matter yet. The Forerunner 55 tracks what you need to stay consistent and avoid the most common beginner mistake: running too hard on recovery days. Recovery Time alone handles that. Once you start following a structured marathon plan or training five-plus days per week, you will feel the ceiling and want to upgrade to the Forerunner 165 or 265.
