    The Garmin Forerunner 45 GPS watch is a reliable companion for runners. With accurate GPS tracking and essential running metrics, it helps users monitor their progress effectively. Its lightweight design and comfortable fit make it ideal for long runs. Additionally, it offers basic smartwatch features like notifications and activity tracking. However, its limited advanced features may not satisfy more serious athletes. Overall, the Forerunner 45 is a solid entry-level option for casual runners seeking a straightforward and affordable GPS watch

    This is a vast improvement from the Forerunner 35. The band is a lot more resistant to breaking. I had to replace the band three times on the 35, and the last break caused me to purchase the 45. I like the body stress, heart rate, and accurate step count. I've only used it for running once, but it does keep accurate stats. I can't figure out the message compatibility, but maybe one day. Battery life is pretty good also, better than the 35. The color screen is also a plus. Menu navigation is pretty simple also. Definitely recommended.

    I bought this Smartwatch after researching for my needs, mainly for tracking daily steps. It does so much more! Also, it's compatible with my Go365 app which is a plus. Battery life is prolonged now that I canceled email notifications, which I don't need. The fit is good with the band even with my small wrist. Price was right and nice to get a Total Tech member discount. I'm very happy with my purchase and recommend the Garmin Forerunner 45.

    I bought the watch for the GPS and incident detection while bike riding which won't be until spring. My only complaint is not having larger sizes for the wrist bands.

    Not Enough and Too Much

    Former marathoner/half-marathoner, getting back into running after almost a 10 year hiatus. I used to have one of those huge, earlier model Garmins that was like a huge block on my wrist, but it was awesome for what it did. I always hated chest straps but like to monitor heart rate during runs. I have an earlier model Mio, which is stylish and great for wrist heart rate alone, but no GPS. Had been using my Iphone for distance and pace, but I hate opening my phone case, finding the app, etc. to check during a run. On training runs, I want to see 4 things and really only 4 things: distance, pace, heart rate and time. And I don't want a chest strap any more. So I researched some (not enough) and settled for the Forerunner 45, knowing that the screens were customizable and, from the photos, it "looked" fairly stylish. I was worried the face would be huge on my wrist, but the pictures are deceiving. The watch face itself is not that big at all. In fact, it is quite small and my wrists are not that big. Unfortunately, the watch band is also small - disproportionately small. It therefore is not very stylish for a man. It seems flimsy and just looks a little weird. That said, it's size and lack of weight make it unobtrusive during a run. The controls are not intuitive but if you can read a guide online, you can figure it out. On a test run, the GPS linked up pretty quick. The wrist heart rate seemed pretty accurate, so the measuring functions seemed okay. The distance was about the same as my Iphone measured. However, the BIG drawbacks are: (1) you can customize the data fields on each running screen BUT YOU ONLY GET A MAX OF THREE DATA FIELDS per screen; and (2) there is no auto-scroll permitting you to move through two screens to get that 4th element of data. This is entirely ridiculous because there is plenty of room for 4 data fields, and non-auto-scrolling is just dumb. (for example, you could make two running screens, one distance, heart rate, pace - and the other distance, time, pace, so only the middle value would change during an auto-scroll - but you can't do that - you have to press a button to change the screen). So, in short, if you want to glance down at your wrist during a run and see time, pace, distance and heart rate - you cannot do it without manipulation. The watch is lightly packed with some other "smartphone" features most people who buy it for running will never use. The treadmill setting is totally inaccurate, particularly if you are not swinging your arms the entire walk or run. There is a calibration setting, but I am skeptical. The battery life seems fine. So, in short, the watch works fine, though a little clunky to set up and manipulate (note 5 buttons - I defy anyone to figure out and remember what they all do). However, it is not a "pure" runner's watch like the older Garmins. The wrist band is WAY to narrow for a man's style and disproportionate to the watch face size. For the price, it is what it is, and I will use this for my runs - not ideal but the best for what I have right now. However, I wish I had been a little more patient and shopped around for something more streamlined for running. If you're someone who is not a quasi-serious runner and are looking for something with those functions and is also a wearable, this might fit the bill. But the key features are the wrist heart rate and GPS, which really only make sense for outdoor runs (or walks), and if you're doing that, you're probably more serious of a runner than this is a running watch.

      To be sure you're using the Treadmill feature properly, please go to support.garmin.com for FAQ's and video's on the functions of the watch. Setting the calibration for the threadmill should be accurate, however, not all treadmills are calibrated the same so unless you're using the same treadmill every time you may need to calibrate it each time. You may also reach out directly to a product support associate from the support link if you need further assistance.

    Solid running watch at this pricepoint

    I really like this running watch. It's simple to use, has an accurate GPS and the Garmin Connect app is solid. One note is that if you're actively tracking with GPS during an activity, the longest the battery will last is about 6 hours. If it's just in passive mode, it'll last 4-5 days between charges. Also, the band wore a sore spot into my forearm, but I think that's to be expected with a lot of these devices.

    I mainly wanted GPS tracking for running and biking, and the ability to receive text messages from my iPhone through bluetooth. This is perfect for that at a reasonable price. it looks stylish enought to always wear it, the face is the right size and there are lots of features selectable with the buttons. The battery life is good. I wish the face had better scratch resistance.

    Bought this for my wife who ended up wanting the smaller 45S after about a month. I was going to buy a smart watch but ended up keeping this one for myself. I've been very pleased. After a few days I could easily get to what I wanted to see on the watch. Everything seems to be fairly accurate. I've run the same route weekly and the GPS is consistent. I like the Garmin IQ app that connects to it. It has lots of good information. The watch doesn't have a swimming activity but you can record as cardio and change on the app. I wish that it was a little brighter when lit up. My eyes aren't what they used to be. It is a really good watch for the price point.

    Battery in full mode actually only lasts 9 hours!

    Moving from a Garmin 35 to a 45- was excited about the upgraded running tracking and the VO2 max info. Complete disappointment as the battery only lasts 9 hours!!! And all the trouble shooting suggests to turn off pretty much every mode in order to get a 1-2 days out of it. Why even have a watch to track and sync with your phone then? When moving from the Garmin 35 battery which lasts up to 2 weeks (still being able to sync with your phone, count your steps, heartrate, activity use daily and such, the Garmin 45 'improvement' was a complete disappointment. I would charge this at night and use the vibration alarm in the morning to wake, and the battery would be nearly dead. Then it takes 1-2 hours to fully charge so I'd have to think about this all the time, esp if I want to sneak a run in after work. There is no way this battery usage is user friendly. I don't need one more electronic to babysit. Being returned and on the search for a better lasting battery option but yet the accuracy of the Garmin with some improved VO2 max tracking and such. Bummer because I love my Garmin 35 and was super hopeful about the 45. Garmin needs to address this major problem!

    Affordable GPS running watch. Had the 920xt before which was very different. Fairly easy to use. Have to get used to the. Http s and some of the new features. Created a workout on Garmin Connect and it was pretty cool how it is displayed on the watch. Only used it once, but so far I’m happy.
