Product description

Premium GPS running/triathlon smartwatch with music.

Forerunner 945 is the GPS smartwatch that's designed for the driven, the qualifiers, the elite. We made this watch for you: the up-at-dawn runners and the conditioned-for-pain triathletes. While you chase your next victory, make sure you've got the right tool for the job.
  • Sync music from select premium streaming services1 or store up to 1,000 songs on your watch, and connect with headphones (sold separately) enabled with Bluetooth® technology for phone-free listening
  • Performance monitoring features include VO2 max and training status with adjustments for heat, altitude acclimation status, training load focus, recovery time, and aerobic and anaerobic training effects
  • Garmin Pay™ contactless payment solution2 lets you make convenient payments with your watch so you can leave your cash and cards at home
  • Full-colour, onboard maps guide you on your run so you never get lost during your workout
  • Safety and tracking features include incident detection (during select activities) and assistance; both send your real-time location to emergency contacts3
  • Battery life: up to 2 weeks in smartwatch mode, 10 hours in GPS mode with music or up to 60 hours in UltraTrac™ mode

Take your music on the go

Take your favourite music with you when you're on the run. Sync your carefully crafted playlists from select premium music streaming services1 such as Deezer, Spotify® and more for ad-free listening. You can store up to 1,000 songs right on your watch and transfer music from your own computer library as well. Then queue up your favourite playlist for easy listening through headphones enabled with Bluetooth technology.

Maximise performance

Forerunner 945 monitors your performance and even offers personalised insight, so you can train smarter, not harder. The smartwatch tracks your VO2 max and adjusts the value based on heat and altitude. Training status evaluates your recent exercise history and performance indicators to let you know if you're training productively, peaking or overreaching. See how your workouts influence the development of endurance, speed and power with aerobic and anaerobic training effect feedback. Recovery time helps you maximise the benefit of your efforts by predicting when you will be ready for your next tough challenge. You can even view your overall training load, which measures your exercise volume from the last 7 days and compares it to the optimal range for your fitness and recent training history. And — new for Forerunner 945 — training load focus sorts your recent training history into different categories based on activity structure and intensity.

An easier way to pay
The Forerunner 945 GPS smartwatch features Garmin Pay, which lets you pay for purchases with your watch. Use it just about anywhere you can tap your card to pay. Now you can leave your wallet behind without missing out on that post-run caffè latte. Just tap and go.

Maps on your wrist
Whether you're running the city streets or riding densely covered trails, Forerunner 945 provides built-in mapping to help keep you on track. Full-colour mapping comes preloaded with map data optimised for at-a-glance navigation and location tracking. And the device also features Trendline™ popularity routing, which uses billions of miles of Garmin Connect™ data to help you find and follow the best trails and routes.

Stay connected and secure
With Forerunner 945, you can head out for a training session without being out of touch. Once paired with your compatible smartphone, you'll be able to receive text messages and see social media updates, emails and more right on your wrist. Safety and tracking features make it easy to share your location with chosen contacts in case you need assistance — manually or automatically with built-in incident detection.

Track more than ever before
For such a lightweight watch, you'll be surprised by everything Forerunner 945 can track. It features multinetwork (GPS, GLONASS and Galileo) satellite reception to track in more challenging environments than GPS alone. It features wrist-based heart rate4 and a wrist-based Pulse Ox sensor5 which monitors blood oxygen saturation levels to support advanced sleep monitoring and altitude acclimation.

Workouts and training plans
Whether you're training for a marathon or something even longer, create your own custom workouts, or download free ones that sync right to your watch. Forerunner 945 also supports Garmin Coach adaptive training plans. These plans feature guidance from expert coaches and free training plans that adapt to you and your goals. It's a foolproof way to get to the finish line. As part of your training plan, it can even help you predict your race time.

Analyse your running form
The Forerunner 945 GPS smartwatch also has the tools you need to improve your running form. The watch measures crucial running metrics such as cadence, stride length, ground contact time and balance, vertical oscillation and vertical ratio. These measurements are the key to understanding your form, so you can bring your best on every run and at every race. Your Forerunner 945 can start tracking these metrics with the addition of a compatible heart rate strap or the compact Running Dynamics Pod, which clips right onto your waistband.

Run, sprint, swim, bike, tri
Change things up with ease, thanks to built-in activity profiles for running (indoor/outdoor), cycling (indoor/outdoor), swimming (pool/open water), cross-country skiing, paddle sports, trail running and many more. Forerunner 945 even has an auto multisport feature that lets you switch sports with a single button press for brick workouts and du/triathlon races.

A few more extras
Forerunner 945 is still an exceptional smartwatch for everything that happens between races and training sessions. All-day activity tracking keeps tabs on your steps and calories and even provides advanced sleep monitoring. For endless personalisation options, Forerunner 945 is compatible with the Connect IQ™ Store, where you can download free apps, widgets and data fields. Check out the Running Power app, which lets you see your running power in real time — as well as after your run.

The Forerunner 945 is not good, it is the best! I changed the Fenix 5 to this and I've been really pleased. All functionalities are significantly faster and less rigid than in the Fenix 5. The only downside is that the battery life seems to be a little shorter than what the manufacturer mentions.

It's not like a road trip game, but there are so many features that you can study for a week ... :) 17.4.2020
Great shopping for your needs
Joni K. 6.4.2020
Overall rating
Comfortable in the hand due to its light weight. Versatile and very informative. At least when browsing the map, it would be good to have a touch screen, but even with the navigation keys, you can do it if necessary. By the way, the physical keys are good and fast to use and always accept the command. A couple of times I have had to turn off the clock when the music has not turned on otherwise.

The top device, almost imperceptibly light, makes the wrist heart rate measurement work great.

I switched to the Forerunner 945 from Applewatch 2. The aim was to have more diverse and customizable sports-related functions. This is realized yes Garmin offer, sports performance, I am tyytväinen and also the fact that the clock is visible all the time. The problems with data storage and integrity between the clock, web application, and phone, on the other hand, came as a surprise. In the Apple world, the phone and clock were always 100% consistent and there was no missing data. This has not been the case with Garmin during the 14 day test period. There are problems with data collection, storage, and display in the phone / web application on all other data, except for sports recorded as your own performances. For example, sleep data on the Forerunner 945 is stored for only 1 night in a 14-day period, timeline data is not stored in the phone app, and is only partially stored in the web application. Exercises will be remembered. Synchronization seems to work; the phone always finds the clock. I keep wondering, there is still hope for intact data in all areas including Garmin.

Great product. Enough data to guide training and monitor fitness. Connect usability is good. The results of sleep monitoring change during the day, but more often only slightly. The functionality of the maps is slow, so it’s “off track” easy to get into the woods. 12.2.2020
Overall rating
A versatile sports watch that positively surprises with its versatility and lacks features. Definitely worth the price. The previous watch was the Forerunner 610, which was definitely worth the upgrade. I recommend!

I just had time to use this, but it would seem to be a very functional device for my own needs. The multisport feature and a wider range of sports compared to the former FR235 have brought great joy. Battery life would also seem to be very good and was one of the biggest reasons to switch to that model. Bodybattery seems to work pretty much right compared to my own feelings. I haven’t tried navigation yet, but the map template is a great feature when you also occasionally come hiking and biking you know where. A big recommendation for the product. The only weakness that comes to mind is the compatibility of my Huawei phone. It's not always possible to get in touch with the phone, but if the phone notifications don't have important information to see on the clock, this isn't a big problem either, as the device syncs nicely over the Wi-Fi network.

The background was that I used the 600 Series Forerunner until 2017. For the years 2018-2019, I used the Apple Watch (Series 3) as a running watch. Now running with the FR 945, half a dozen loops. The first reaction to moving to the 945 - after the Apple Watch - was, "Is this screen really that dim?". And that's it; very dim compared to the AW screen. But I soon realized that the displays on these devices were designed for completely different purposes. The AW screen is "radiant", but it can be recharged every night. The battery of the 945 lasts for a week without recharging, even if it runs loops with GPS enabled (eating power). When the dimness of the screen got over, then the 945 has met all expectations. One big difference compared to AW is the sturdy buttons on the watch, which can also be used with fingers in hand. I don't miss the touch screen on the running clock! When running, the 945's display is clear in both light and dark. After the run, I don’t bother the clock anymore, as examining the collected data is anyway much more convenient from Garmin Connect or Strava, where the data is automatically transferred.
