The Short Version
The Garmin Forerunner 645 Music is not the first GPS watch with music that has come on the market, but it is conveniently the best, with excellent sports tracking capabilities, provided by the extra space for music and an eye-pleasing design that fits every smartwatch. One can not say that the rounded features of the Forerunner 645 Music are the best running watch ever.

Things We Like
- The new music feature is well integrated and easy to handle. It only takes a few minutes to transfer music, podcasts and audiobooks.
- Garmin has integrated all the advanced running features of the more expensive Forerunner 935 and Fenix 5 watches, including lactate threshold measurements, a virtual racing pacing mode and a tracking sensor (compatible sensor) is required).
- The design is Garmin's best yet, with a stylish silver bezel and a smaller profile than the 935 or Fenix watches. This watch can be worn everywhere.
- You can use the Forerunner 645 Music to create and track simple interval workouts, and more complicated sessions can be set up and synchronized with the Garmin Connect app very quickly, which will then guide you through the process.
- Allows daily tracking of activities with goals that automatically adjust to your past activities, and the information is clearly displayed on 645 Music and in the Garmin Connect app.
- The battery life is good at 1
Things we do not like
- The 645 Music lacks some features of the 935, including Open Water and Triathlon modes and support for bike performance meters. The news is pretty clear: Garmin wants triathletes to buy 735XT, 935 or Fenix watches.
- Occasionally the 645 Music connection with my Bluetooth headphones broke off. Usually only for a second or so, but during a race there was an annoying five-minute spell.
- Streaming services are not yet supported in the UK, and there are plans to introduce only Deezer, not Spotify.
- Garmin Pay remains limited to only one bank in the UK at the time of writing – Danske Bank. Fitness brands like Garmin and Fitbit have a hard time comparing themselves to Apple when it comes to contactless payment with the watch.
Garmin Forerunner 645 Music In-Depth
Using the Garmin Forerunner 645 Music For Running
The Forerunner 645 Music senses just about everything, but throws the kitchen sink into its running range. There's a lot to say, but if you're about to skip, you should know the following:  The 645 Music has every tracking feature that a runner might want and gives them a soundtrack.
You can do this as you can choose many data screens and store them with up to four values per screen. Taking a look at all the customization options would take more time than you, dear reader, and I can do without them, but besides the defaults such as time, distance, pace, and heart rate, you can have screens that depict your route or route It shows you a course to track, a virtual pacemaker (the only screen I use in races), guided training information, and detailed running dynamics. The latter requires a compatible sensor such as the HRM-TRI from Garmin or the Foot-Pod and displays advanced information such as your contact time with the ground while running. It is not intended for casual or even damn serious runners, but its inclusion shows that 645 Music itself is suitable for the most obsessed.
You can also watch a screen dedicated to your music and watch it on the CD at any time by holding down the button. Adding and organizing music on the device is more detailed in the Smartwatch section below. However, if you use them while walking, the main focus is on the influence of the battery and the good connection of Bluetooth headphones. The battery needs a considerable amount of success – music plus GPS means it lasts five hours, compared to 14 if only GPS is used. For most races this is still sufficient, even if a marathon could be scarce, but I have found that the Forerunner 645 Music at least meets the requirement of five hours. So you know that you have GPS for every hour and 20% lose music and can turn off your music if you need longer GPS.
The connectivity of Forerunner 645 Music was mostly impressive. I've used it in several runs and a half marathon as the only source of entertainment, and although it turned out occasionally, it never completely failed me. At the beginning of the half, I had difficulty maintaining a connection to my headphones for five minutes, possibly because of the large number of people who were putting on headphones around me at that moment, but just when I thought I would do it Without Music for a whole race it came on and the connection stopped from then on. I also need to highlight how easy it is to transfer podcasts to 645 Music as they make up most of my running entertainment and it's extremely difficult to access an Apple Watch that requires you to use third-party apps.
The 645 Music allows you to track a set route on the clock during the run, with a breadcrumb path and a small arrow. You can activate these routes yourself during the run and enable a back-to-start feature that is very useful when running in a new area. To create full routes, you must use the Garmin Connect website, but you can use the Garmin Connect app to create fast routes based on direction and distance, and synchronize them with your watch.
Workouts can be created through the app or website synchronized to the clock. Impressive that the creation takes no time – I made it once on the way to the racetrack, when I realized that I had not started my workout. You can also create and track interval workouts on 645 Music yourself on a special screen, count down each section, and keep you up to date when you set a tempo or heart rate target for specific parts of the session.
The session is over. The Forerunner 645 Music will highlight all highlights, such as a new fastest 5K time or an improved VO2 maximum. There is also an ongoing analysis of the relationship of your changing fitness (based on your VO2 max) to your training load. It tells you if your work is productive, unproductive, and sufficient to sustain your fitness. Breeding condition (peaking), recovery assistance (recovery), hyperbole (overreaction), or letting go (entraining). It also tells you how much time you need after a session to recover, and your estimated best times for 5km, 10km, half marathon and marathon routes.
In short, the Forerunner 645 Music is the ultimate training partner for runners. The advanced tracking features of top GPS watches are combined with the music normally found in smartwatches. In the past, you had to choose between the two – the Fitbit Ionic and the Apple Watch Series 3 are great for music and other smartwatch functions, but are not as good for running tracking as the Forerunner 935, which in turn I do not have music. The 645 Music offers the best of both worlds.

Using the Garmin Forerunner 645 Music For Cycling
You can customize your data screens as you run, and the Forerunner 645 Music connects to different heart rates via ANT + and Bluetooth -, speed and cadence sensors ago. Heart rate monitors worn on the wrist can be problematic as the forearm is lashed while cycling. However, I found that heart rate measurement during cycling was better than I expected. During my commute and an interval session inside, the 645 Music was accurate. although I have not tried it on long outdoor rides. It is easy to pair a chest strap if you want to avoid doubt about the readings.
There is no support for the power meter, which will be a disappointment for cyclists, but in keeping with Garmin's positioning of 645 Music as a running clock. instead of one for triathletes. However, cyclists will enjoy the opportunity to watch Strava segments on 645 Music. So if you're fighting for a particular KOM (King of the Mountain) in the app, the clock will show your progress live.
Using The Garmin Forerunner 645 Music to Swim
Before getting wet, look for a pool at least 17 meters long. This is the minimum size for which you can set a length for the 645 Music. For most enthusiastic swimmers, no big deal, but in urban gyms, it's not surprising to find 15-meter pools – the two I use most often are 13 and 16 feet.
Once you start swimming, heart rate monitoring on the 645 Music is disabled, which is not consistent with other manufacturers. Suunto, Polar, Samsung and Apple devices try to track heart rate while swimming from the wrist. This is not always successful, but usually good enough to make it a worthwhile feature.
As with all sports modes of 645 Music, you can do this Set up your data screens for swimming and follow the training in the water. Afterwards you will receive graphics and more details on important swimming statistics like SWOLF. Apart from the heart rate, indoor swimmers will get everything they need with 645 Music, but there is no open-water mode.

Using the Garmin Forerunner 645 Music to Track the Activity
The Forerunner 645 Music is indeed a running watch, but obviously no watch that only should be worn while running. It captures your heart rate around the clock, displaying a graph of the last four hours (color coded by the heart rate zone you were in) along with all standard activity statistics such as steps, calories burned, cleared floors, and weekly active minutes (moderate and vigorous) Activity broken down). It will also track your stress with a measurement based on heart rate variability.
You can set the goals for steps, active minutes, and climbing floors, and set steps to automatically adjust them to your past activities. Try this, for example, during marathon training, and your goal will quickly rise to 18,000 steps.
The Forerunner 645 Music is first and foremost a sports tracker, but its daily tracking is what else you want Find on the market.
Using the Garmin Forerunner 645 Music as a Smartwatch
645 Music is added to music via Garmin Express, which you must download to your computer. You can easily select the music or podcasts you want to add. Garmin Express also picks up your iTunes playlists so you can sync them directly to your watch. According to Garmin 3.5 GB of storage space available – about 500 songs. 645 Music is expected to be connected to the Deezer streaming service by the end of April or early May, if there are no delays. There is no live streaming on the clock, as it is not activated as for the Apple Watch 3 for mobile phones. However, if you link it to a Deezer account, your playlists will be updated when you're connected to Wi-Fi so you can play them offline. A good way to make sure that you do not use the same music for each run. Spotify would be more useful to most people in the UK, but it's not work yet.
645 Matt's other standard smartwatch features include notifications, and there are a few apps and alternate dials available in the Connect IQ store, including Uber, although these focus primarily on sports.
The other important smartwatch feature is Garmin Pay, but at the time of writing, this is limited to customers of Danske Bank in the UK. Congratulations, if you use them. Other banks should follow, but the timeline is unclear and seems to be a very slow process.
Using the Garmin Forerunner 645 Music as a Heart Rate Monitor
The Forerunner 645 Music captures your heartbeat throughout the day, both the load and the measurement of resting heart rate. After trying out several Garmin devices with stress tracking, I have to say I did not look at it after the first few days, but the resting heart rate value is useful as it's a good gauge for your cardiovascular system Fitness is – if you have your resting heart rate drops, your fitness is likely to increase. It is also useful, albeit sometimes alarming, to display your daily resting heart rate on the clock during the past week. Worrying, because on the day after a big night out the following day, I noticed a noticeable increase in my resting heart rate. Alcohol, right?
While tracking an activity, you can monitor your heart rate and / or heart rate ranges on a customizable data screen, and there is also a special screen with a color-coded meter that shows your heart rate and heart rate. Indicates which zone you are in , You can also train by heart rate zone when you set up a workout in the Garmin Connect app. This is useful if you do not like to use tempo to judge the intensity while running, or not because you & # 39; In a hilly area where you will work hard, even if you walk slowly.
I never had any issues with the accuracy of the 645 music heart rate measurement in all the activities I tried. While walking, I found it reliable enough that I did not have to wear a chest strap. Even during the interval sessions there was a small delay between the increase in effort and the correspondingly increasing reading.

Using the Garmin Forerunner 645 Music for Sleep Tracking
I think Garmin has never really cracked sleep tracking. All the Garmin trackers that I have tried have a hard time distinguishing between sitting or reading in bed and sleeping in bed, which means that my total number of hours is always artificially high. This remains the case with 645 Music. You'll get a graphic representation of your move during the night, so you can actually see when you fall asleep and wake up, even though 645 Music thinks you fell asleep earlier, and you also get all the time you spend in the Spend light or sleep in the deep sleep. It's an ok sleep tracker, but no more than that.
On the positive side, the 645 Music is very light and comfortable to wear, and I've found that my wrist did not get hot or sweaty overnight.

The Garmin Connect App
This is probably my favorite fitness tracker affiliate app, and if all were on it, I probably would not with Strava employ the latter. Garmin Connect shows all your daily statistics and activities clearly on the start page through a series of colorful cards. You can click to get more detailed information about a specific run or your step count in the last few days, weeks, or months. For seven days, you will get an overview of all the important statistics on the home page, including calorie and pace averages, and total distance and distance traveled. In addition, the app syncs easily with Strava, so your activities are automatically transferred.
However, I found that I had more trouble syncing 645 Music with Garmin Connect than with other Garmin trackers, especially when transferring long runs. At Vivoactive 3, Forerunner 935 and Forerunner 35, I found that my activities were often synchronized even before I managed to take my shoes off when I got home. However, at 645 Music, I often had to open the app and update it a few times. It's not a big deal, just a surprise.
How often do I have to charge it?
Garmin gives the battery life as 14 hours GPS or five hours GPS plus music or five days as a smartwatch. Setting the music aside turned out to be twice a week, based on running four or five times and getting to work on the bike. But who wants to put the music aside? It's the point of the matter. Listening to podcasts or music from 645 Music throughout my run cost me at least three loads a week.
Where can I wear them without people laughing at me?
The Forerunner 645 Music is a great-looking watch. especially considering that it has five buttons. Keys make it much easier to do activity than a touch screen, but usually label a device too sporty to wear anywhere. The 645 Music defies this convention – it's as stylish as any other smartwatch.
Should I buy something else?
The Garmin Forerunner 645 Music is conveniently the best running watch with music that is just available you are looking for, stop searching. Other options such as the Apple Watch, Fitbit Ionic and TomTom Spark 3 (with music) all miss the 645 tracking features that can only be surpassed by top trackers such as the Forerunner 935 Moment.
If you're a runner and do not care about music, the obvious option is the Forerunner 645, which is £ 50 cheaper, but it's also worth looking for cheaper predecessors like the 235 or 35. or trackers of other brands such as the Polar M430. These may not offer as many features as the 645, and they are not so stylish, but they are still great running watches.
The Forerunner 645 Music moves past runners and is a great daily activity tracker, but you do not just have to spend 400 Euros on it – Fitbit, Garmin, Misfit and many others make great trackers for over 100 Euros daily.
If you're a triathlete, you'll need to take the many clues from Garmin along your way and invest in another watch – the 935 or the 735XT – or wait for a musical multi-sports watch to arrive.
