Garmin Forerunner 945 Review (2023)

If you’re diving into the world of triathlon watches, let’s chat about the Garmin Forerunner 945.

First released in 2019, obviously updated vigorously afterwards, this bad boy is like the Swiss Army knife of triathlon gear – packed with features for swimming, cycling, and running, and even keeps an eye on your sleep and stress. But, don’t get too cozy with the price tag; it’s on the higher end, making it a serious investment for your training arsenal (unless you can grab it when on sale). Sure, it’s user-friendly and comfy, but before you commit, no gadget is perfect – do your homework, especially on its GPS accuracy and heart rate monitoring, to see if it truly fits your triathlon dreams.

Is It Cheap or Expensive?

Alright, let’s talk money. The Forerunner 945? It’s definitely on the pricey side. Launched originally at nearly 600 bucks and now around 400, it’s not something you’d buy on a whim. But, consider what you’re getting: a high-end, feature-rich triathlon watch. It’s like investing in a high-quality bike – costly, but can be worth it for the serious athletes. Try to grab this one on a sale and you’ve got yourself a bargain.


Easy to Use?

Now, is this thing a nightmare to navigate? Surprisingly, no. It’s quite user-friendly, and I’ve found it pretty comfortable on the wrist. Sure, it’s got a ton of features, but Garmin didn’t make it a puzzle. They’ve done a solid job making sure you don’t need a PhD to use this watch.


Triathlon Modes?

For triathlon training, this watch is a dream. It’s got dedicated modes for swimming, cycling, and running. This isn’t just a jack-of-all-trades; it’s a master. It understands the nuances of each sport, making it a perfect companion for triathletes.



Waterproof? Absolutely. It’s rated Swim, 5 ATM, so it’s ready for your pool sessions and open-water swims. No need to baby this watch around water.


Reliable GPS?

The GPS, though… I can’t exactly vouch for its pinpoint accuracy, especially for cycling and running. It’s good, but don’t expect military-grade precision. It’ll get you where you need to go, but sometimes the route might be a bit… scenic.


Heart Rate Monitor?

Heart rate monitoring is a tricky one. It’s got a wrist-based monitor and plays well with chest straps, but I can’t say how it performs continuously during training. It’s like expecting consistent performance from your internet provider – mostly good, but sometimes you’re left wondering what you’re paying for.


Long Battery?

Battery life? It’s solid. 36 hours in GPS mode means it’ll last through your long training sessions and even a full race day. It’s the marathon runner of batteries.


Quick Transitions?

Now, about transitions… While there’s no explicit info, its ease of use and multi-sport modes hint at a smooth transition experience. It’s like having a quick pit stop in a race – efficient and necessary.


Custom Display?

Customizable display details are a bit murky. It’s like Garmin forgot to brag about it. So, it’s a bit of a grey area – could be great, could be average.


Data Sync?

The Forerunner 945 syncs with apps and devices for data analysis like a charm. It’s like having a personal data analyst, constantly crunching numbers to optimize your training.



Alerts for pacing, heart rate zones, training duration – they weren’t very forthcoming with this info. It’s like knowing there’s a secret menu, but no one will tell you what’s on it.



Durability? Again, specifics weren’t easy to come by. It’s like they’re saying, “Trust us, it’s durable,” but without showing the proof. For a high-end watch, I’d expect it to withstand the rigors of triathlon training.


Sensor Ready?

Compatibility with additional sensors? It’s got you covered. Whether you want a chest heart rate monitor or something else, this watch is ready to connect. It’s like having a bunch of USB ports – always handy for more gadgets.


Would I Recommend It?

Would I recommend it? Yes, but with a caveat. It’s a great tool for serious triathletes, but make sure to do your homework. Look into the GPS accuracy and heart rate monitoring effectiveness.
