I have been running for nearly 30 years. For most of that time I ran by feel — no data, no metrics, just miles and effort and experience. I thought that was enough.
Then I got the Garmin Forerunner 265 and discovered how much more I had to learn!
This is my honest Garmin Forerunner 265 review. This watch changed how I train — and why I think it is one of the best investments a serious woman runner can make.

First Impressions — The Screen
Let’s start with something that does not get enough attention in watch reviews — the screen size and readability.
The Garmin Forerunner 265 has a big beautiful screen that is genuinely easy to read while you are running. I have the 46mm version and the display is clear and bright in all lighting conditions — direct sunlight, early morning darkness, everything in between. For women over 50 who may need a little more screen real estate to read data quickly mid stride this matters more than most reviewers acknowledge.
The touchscreen is responsive and intuitive. Navigating menus, starting a run, checking your stats — it all feels natural and quick. No squinting required.
Battery Life That Actually Lasts
My Garmin Forerunner 265 charge lasts more than a week. One week of daily runs, sleep tracking, notifications, and everything else — and I am not scrambling to charge it before I head out the door.
For runners who use their watch every single day this is a significant practical advantage. A watch that needs charging every two days is a watch that is going to die on you at an inconvenient moment. The 265 essentially eliminates that concern.
GPS That Connects Fast
Before the Garmin 265 I had experienced the frustration of standing on my porch waiting for a GPS signal to lock before I could start my run. That waiting is gone.
The GPS on the Forerunner 265 connects fast — within seconds of stepping outside I am ready to run. On early morning runs when I am out the door before the sun is fully up the last thing I want is to stand around waiting. The quick GPS lock means I just go.
Training Readiness — The Feature That Changes Everything
Not all Garmin watches have Training Readiness and this is one of the most important reasons to choose the Forerunner 265 specifically.
Training Readiness is a daily score that tells you how ready your body is to train based on your sleep quality, heart rate variability, recovery time from recent workouts, and overall training load. It gives you a number and a recommendation — push hard today, take it easy, or something in between.
Before I had this feature I guessed at how my body was feeling. Now I have data. And the data has changed how I approach my training days in a way that has made me both a smarter and a healthier runner. Some days the score says go hard and I go hard. Some days it says recover and I respect that instead of pushing through.
VO2 Max Tracking — Watch Your Fitness Improve
VO2 max is a measure of your cardiovascular fitness — essentially how efficiently your body uses oxygen during exercise. It is one of the best overall indicators of aerobic fitness available and the Garmin Forerunner 265 tracks it continuously.
In the four months since I started using this watch paired with the Runna training app my VO2 max has improved by 3 points. That is not a small number. That is measurable evidence that my training is working — that the early mornings, the easy runs I am finally running easy enough, and the structured workouts Runna has been prescribing are actually making me a fitter runner.
Seeing that number climb is one of the most motivating things I have experienced in my running life.
Run Productivity Scores
Beyond VO2 max the Garmin 265 gives you run productivity scores after every workout — a rating of how effective your run was based on your effort, your heart rate, and how it fits into your overall training load.
This feedback has genuinely changed how I think about individual runs. Not every run needs to be a hard run. Not every run needs to push your limits. The run productivity scores have helped me understand which runs are building my fitness and which ones are recovery — and that understanding has made my training more intentional than it has ever been.
The Runna Integration — A Game Changer
The Garmin Forerunner 265 pairs seamlessly with the Runna training app and the combination is something I recommend to every serious runner.
Runna builds your personalized training plan based on your goal race and current fitness level. It then pushes each day’s planned workout directly to your Garmin — the warmup, the intervals, the target paces, the cooldown — all right there on your wrist without needing to check your phone. As you run the Garmin delivers real time pace feedback through your earbuds telling you whether you are going too fast or too slow.
The Runna app is also adaptive — it watches how you are executing your workouts and adjusts your training paces accordingly. After two months of training it increased my target paces and projected a faster race time based on my actual performance data. That kind of intelligent coaching used to require hiring a personal running coach. Now it fits on your wrist.

Sleep Tracking
The Garmin 265 tracks your sleep every night — duration, quality, sleep stages, and how it contributes to your Training Readiness score the next day. As an active woman over 50 sleep is not just rest — it is recovery. Understanding how your sleep is affecting your training readiness has been a genuinely useful addition to my daily routine.
Who Is the Garmin Forerunner 265 For
This watch is for serious runners who want more than a step counter and a heart rate monitor. It is for women who are training with intention — who have goals, want data, and are ready to use that data to run smarter.
It is particularly well suited for women over 50 who want to train effectively without overtraining — the Training Readiness feature and run productivity scores are essentially built for exactly that. Knowing when to push and when to recover is arguably more important after 50 than at any other time in a running life.
If you are ready to move beyond basic tracking and into genuinely intelligent training the Garmin Forerunner 265 is the watch I recommend without hesitation.
The Bottom Line
Nearly 30 years of running and the Garmin Forerunner 265 is the most impactful piece of gear I have added to my running life in recent memory. The big readable screen, the week long battery, the fast GPS, the Training Readiness feature, the VO2 max tracking, and the Runna integration have made me a smarter, more intentional, and measurably fitter runner.
Three points of VO2 max improvement in four months. I’ve worked hard for that, and I’m proud of it!
