I’ve been a Garmin Fan since the first forerunner was released. I’ve had various Forerunner versions and this one is by far my favorite. The fast GPS pick up is by far my favorite feature. As I am a seasoned athlete, the daily workout tips and suggestions were annoying until I turned them off. The only thing I don’t love is the case size. The large is a mm larger than the 235 Version (46mm vs 45 mm) and the small is 1.5 mm smaller than the 245 version (41mm vs 42.5mm). The large is too big for my wrist and the small is too small but a workable option compared the the large version. I feel like in trying to make this watch more available to all people; they made it ideal for the two extremes of body sizes and the middle group got the shaft this go-round. The watch would be perfect if it was anywhere between the 42.5mm of the 245 and the 45 mm of the 235.
Aesthetically this is the best looking of all the forerunner versions in both sizes; but on my wrist the large is too big and won’t track my wrist heart rate correctly because my bone doesn’t allow the watch to lay flat. The small looks too small for my wrist. 🙁
I didn’t realize how much it bothers me. I had to get a new Garmin when my was broken in a bad accident…. Along with a few of my bones… 😬.
I’m a bit disturbed by how much the too small aesthetics of the watch bugs me and wish I would have just bought another 245 because apparently aesthetics are more important to me that the altimeter and quick GPS pick up. 🤷🏻♀️

This is my second Garmin forerunner. I put about 6000 miles on my first one and decided to get a more soffisticated watch fir the second one. This watch really helps you track a large amount of data about your running, sleeping and general well being. If infers suggestions on how to make your workouts as beneficial to you as possible. I am very pleased with my new 255s garmin forerunner. I am only about three weeks into using it and it is excellent. I hope to surpass the 6000 miles I put on my other forerunner. You can customize the watch face in a large variety of ways and it will show you only the things or items you want. OUTSTANDING!!

Good fitness tracking. Geared to runners vs. hikers, although it has a hiking profile I use. Pace does not work when going less than a mile an hour on strenuous trails. Sleep stages seem off sometimes. The manual is required to learn the many features and functions.
Overall I find this a very useful watch for daily use, health/fitness tracking, and activity tracking. I like that I can manually pause it during an activity when stopped. I don’t use the auto pause because it turns the tracking off when going slow.

I love this watch. It is the perfect balance between features and it’s price point. For the price point it includes a lot of features. It took me a moment to get used to the MIP screen but I appreciate it and would buy it again. The battery life is outstanding and something I’m most thankful for especially coming from charging my Apple Watch every other day. I used my Apple Watch as a true “smart watch” – I allowed all of my phone notifications to come through, however on this Garmin I have all of those features turned off, I didn’t want that nor do I need it. I appreciate most having all of Garmin health features and the app is even more user friendly than apple’s. I’ve always used farming platform to record my fitness activities and I’m happy to be onboard with their smartwatches. Garmin does everything and more, in my opinion.

Need to know how to use it first, googling and watching youtube. After a while it’s good to go!
Charging was fast. More importantly with my small wrist the size seems good.

The battery life is much better than my old 235 and the features work well. It has all the modes that the serious runner needs. Five stars.

I love this watch. Starting from the fit, it’s comfortable, light, and the perfect size for my smaller wrist. The straps are soft and comfortable so it doesn’t feel like it’s trying to move to the side of my wrist like watches often do. I love the colour and slight orange accents – understated and cool looking. The buttons are clean and crisp and responsive, and the menu layout is intuitive. The running dynamics are amazing – I’ve learned more about my running in the last week than in the 16 years I’ve been running. Power is especially interesting and I’ve used it to build custom interval workouts. I’m not using the cycling features because I have my garmin edge, but it easily broadcasts my HR to that device with fewer button pushes than my lazy device – quick, easy, effective. Insights into v02 max (different for cycling and running, interesting) are surfaced to the watch ad well.
I’ve just started an adaptive training plan – can’t say mich about that yet other than I love the concept. It is odd to sign up for a training plan and not see the plan – you can only see the next few workouts as it will be adapted to your needs as you go. Looking forward to seeing how that goes.
Predictive paces seem fast. Maybe it’s right, would be nice. Will try pace pro in the future to see.
A few notes since this is a triathlon watch – no predictive paces for triathlons, seems to be only for runs and cycling races. No training plans for triathlons. I’m doing a run plan on tne 255 and a bike plan on the edge, but they aren’t integrated and don’t respond to one another. I’ll also be doing a cycling plan on Zwift and that’s just outside of this universe so I’ll have to manage that integration on my own. That’s all fine, but it will be interesting to see if / whether my run plan adapts to my fatigue or fitness changes from the cycling plan. Yesterday I had a gran fondo, which was on the garmin race calendar, yet it still told me to do an easy run as part of my run training plan. It should be easy for her watch to move that run knowing I had a long hard rice to do.
Bottom line – fit, comfort, style, and functions are all amazing. Great purchase, very happy.

The Garmin Forerunner® 255S has truly become my absolute favorite smartwatch and has been a key tool through my fitness journey, here’s why I love it:
Adapting to My Workouts:
Although labeled as a running smartwatch, it effortlessly fits into my diverse workout routine. Whether I’m hitting the gym, practicing yoga, or going for a nature walk, it tracks my progress with accuracy.
Feels Like Nothing:
The lightweight design is a game-changer. During workouts and even during sleep, I barely notice it’s there, allowing me to focus solely on my routines.
Accurate Insight:
From heart rate monitoring to sleep tracking, it offers insights that help me tailor my workouts effectively and monitor my health data reliably and easily. Knowing I can rely on its data keeps me motivated.
Part of My Day:
Its sleek profile and customizable faces make it not just a workout companion, but an everyday accessory that reflects my style.
No Worries About Charging:
One thing I appreciate is its impressive battery life. It’s a relief knowing I can wear it all day without needing to recharge constantly. For my use, it lasts 11 days before needing a charge. When It does need charging, it charges FAST!
In short, the Garmin Forerunner® 255S is more than a gadget; it’s a personal fitness partner. It adapts to my routine, offers accurate insights, and feels like a natural extension of my active lifestyle. Whether I’m lifting weights or running errands, it’s a constant companion that helps me stay on track and motivated. I highly recommend this watch!

I have had this watch for 2 months now and it has by far been the best smart watch I have ever owned. As a runner, this watch if much more effective in recording my runs and provides much better insights to my workouts. The charge lasts a long time too, which is really nice. I only charge it about ever 4 or 5 days. Overall, really recommend this watch if you’re wanting to know more about the details of your workouts and your overall health. There’s a lot it has to offer!
