"Garmin is a superior fitness watch. ... Especially if you are running every day."


"it has a lot of additional activity features I like (e.g. tracking outdoor swimming, biking , training plans etc)"


"the load tracking and suggested workout feature alone is worth it. ... The battery of data signals you get to tailor and improve your training is worth the switch alone"

"I had my FR 45 for 5.5 years and now my dad has it and the battery is still in great shape for its age. 😁"


"i’ve had it for 3-4 years and it works great."


"near indestructible"

"Oh, and the battery lasts days even when exercising a lot (weeks without excercise)."


"Battery good enough to withstand long run in winter (AW tended to have problems in 30+ km runs in cold, not Garmin) ... Forerunner asks me if to go to power saving mode, when there are "just two days left" :)"


"I get close to a month from my forerunner on standby - about 2 weeks with daily workouts. ... the battery life lasts a really nice length of time ... As a fitness wearable Garmin... destroys Apple on battery life. ... There’s really no sensible person running Tris or Marathons using an Apple Watch. The battery life is too poor to last reliably. If you go to the starting like of a marathon you’re really only going to see actual fitness brands on wrists due to battery life alone."

"I can't tell the forerunner is on my wrist. ... It took me a while to get used to the heft of the fenix. It it noticeable while running or any activity in which your hands swing."


"if you buy something lighter like venu, forerunner or fenix S version it will not interfere with the game at all."


"Forerunners are much lighter weight and therefore much more comfortable to wear."

"the Garmin is far worse from a smartwatch perspective ... my AWU2’s cellular connectivity is above and beyond the thing I care most about on long, remote runs."


"if you have to take your phone anyway, there's a much better device on you for making calls. ... apple watches can have sim cards and place calls *without* having your cellphone on you. that's a real use case -- go for a run, leave the bulky phone at home."

"I had it for 3 years, and the plastic bracket that holds the wrist strap pin broke. ... The part the oin fits into snapped off."

r/AdvancedRunningHow often do you replace your running watch?
6 months ago

Seems like I am replacing my watch every 2-3 years. Battery is always the reason. Have gone with the base models of the garmin forerunner (35,45,55) then finally upgraded to the 200 series most recently.

r/GarminGot a Forerunner 255 to accompany me on my weight loss journey. Loving it!
11 months ago

I had a Forerunner 45 and then upgraded to a 255 and I am very confident that a 255 is the one to get before the return diminishes verses investment. The daily suggested workouts and the PacePro have transformed my training (runner here) but when I look at Garmins that cost $1000+ I can’t imagine what a watch would need to do for that to be worth it? Really hope you enjoy your 255 it helps you achieve all of your goals!!

r/XXRunningIs Garmin worth it?
5 months ago

I've really liked all of my Garmin watches! Check out anything from the Forerunner line, like the Forerunner 55. And highly recommend getting a refurbished/used one to save money, if that's an issue for you. You can get the 55, 45, or 35 for a pretty good deal refurbished/used.

r/XXRunningCheap Tracker/Watch to Monitor Real-Time Pace

I would look for a used or refurbished Garmin Forerunner 35 or 45 (whatever you can find for cheapest). Also just to note, GPS is what allows watches to accurately measure distance and pace, so you’ll want a watch either GPS. However for the ultimate cheapest option, if money is really limited, consider just using a running app on your phone instead.

r/XXRunningCheap Tracker/Watch to Monitor Real-Time Pace

You're welcome! And yeah I agree, using a phone is super cumbersome. Having a watch is so much more convenient! Even though they can be pricey, I think they're a good investment. And the longevity of Garmin Forerunner watches is quite good in my experience. And also they stay fairly valuable as long as they still work, so if you eventually decide to upgrade to different model, you can still sell your old one!

I liked my Garmin forerunner 45, which from what I can gather was there least advanced model (I think it's the 55 now). It's also the least expensive, but I think you get alot of bang for the buck with out all the bells and whistles. GPS was almost always on point, had one bad experience, but other than that it worked well. A little slow when conneting to the satellites. With the chest band the I got all the data I need from my runs. Tried the wrist monitor once for comparison but it was of like 20 beats. Don't know if thats what you are looking for, but hoping it helps!

I did some gym work with it. From what I recall it wasn't a problem. The 45 is a small watch.

r/firstmarathonCheapest functional running watch
6 months ago

Older Garmin watches work fine, I regularly see runners with the 2015 Forerunner 235 at races. And used models will be fine, albeit older watches may have reduced battery life simply due to age. That’s the nature of rechargeable batteries I’m afraid, and it applies to all brands. I would recommend a Forerunner 45 as the minimum, or a 55, and if you can get a 245 in budget then even better Whichever watch you choose, go to [DC Rainmaker](https://www.dcrainmaker.com/) and search for his in-depth review of that model which typically includes a video. They will tell you all about the functions, how to use it, what it can do etc.

r/GarminLooking into the Garmin Venu 2s
6 months ago

I have the Venu 3s and it is rated as a solid running watch on test forums. I run using the Garmin Coach 3 times a week and find the statistics completely sufficient. Previously I only had an FR 45 that could do even less. So it was a big upgrade for me. (But to be honest, the professional statistics would be too much for me, so not absolutely necessary). But if you can't wear your watch that often, then the Venu is too expensive. Then I would also go for the cheaper FR models. I mainly wanted something more stylish for everyday wear, as I feel like I wear my watches 24/7, which is why it suits me very well. 😊

I can't confirm. I had my FR 45 for 5.5 years and now my dad has it and the battery is still in great shape for its age. 😁

r/dysautonomiaBest fitness tracker?
10 months ago

I love Garmin. Have had an old Forerunner 45s for a few years and planning to upgrade for the 255S version soon. They’re more sports trackers so their features are geared to that but Garmin also has the Venu or Vivoactive lines that are more smartwatch-y. Other than that I heard good things about FitBits and their sleep/lifestyle tracking but haven’t tried myself.

My Forerunner 45 from 2018 is still going strong too! Though I use Smashrun, not Strava.

r/GarminWhat Garmin watch do you own and why?
about 1 month ago

45s>265>epix pro gen 2>instinc 3 45>vertical 2>255>enduro 3. That was my way. After couple years can say- 255/955 mips are one of best ever for lot of sports and mip lovers, their amoled sibilngs are also great. Instinct 2,3 also great rugged tanks. A little smaller screen for me (like 6-8 metrics for one screen during runs, ins.can go up to 4-5). F7 pro or 7x for bigger wrist, epix pro gen 2- fanstastic options but bulkier- just dont swim with them because buttons can get smooshy (mine did!). Flash and newest opt.hr great! Dont like too bright screens on vx1 and 970, and lame battety. Now enduro 3 comes in a way. It is truly fantastic. Smaller wrist about 17.5cm and it is not heavy like epix pro gen 2 47mm. Battery is 40days with little sun a day and 1h of gps 6 times a week. Crasy. Didnt now what to except, many here adore it, but now- I am one of them.
