Here we have the full Garmin Forerunner 945 specs compared to the Garmin Forerunner 935 and Garmin MARQ ATHLETE. We’ll start out with some commentary of the new additions found in the 945.
Return to the Full Garmin Forerunner 945 Review
Garmin ‘Pro’ MultiSport – State of Play
The earlier, Garmin Forerunner 935 was the best triathlon watch. It did all the right sporty things for broadly the right price.
It ticked all the boxes for workout planning, workout execution and working within Garmin’s open-enough platform to move your data to specialist 3rd party sites if that was what you wanted. It connected to the right sensors, in the right ways and it connected you socially and competitively to others. Factor in a ‘correct’ 5-button, non-touchscreen, lightweight format and an increasingly useful 3rd party app infrastructure then it soon became a compelling ‘must have’ option for a serious triathlete.
Most of you reading this have probably already got a 935, and can broadly guess what the Forerunner 945 does. for sure, it does the SAME and also more than the 935.
However, some seeds of doubt can be sown. Maybe the Fenix 5S Plus was better for the thinner-wristed amongst us? Maybe the recent MARQ Athlete will be for those wanting a high-end case? Maybe those CIQ apps and new firmware updates are starting to slow down my 935? Maybe that 2-year-old battery might not get me through an Ironman any more? Maybe.
The Garmin Forerunner 945 is broadly the same as a 935 but on techy steroids. It’s got improved hardware, slightly improved triathlon-related real sports functionalities and notably increased smart functionality.
It’s been future-proofed with a faster processor and longer-lasting battery package. Some of the tri stuff has been tweaked slightly and the Firstbeat physio algorithms improved and extended to match the new ones we heard about earlier this year on the MARQ.
But the big difference is that the new Garmin Forerunner 945 is moving more towards being a LIFESTYLE watch. It’s become that 935-Plus model we never had which means that it now has MUSIC, MAPS and PAYMENTS. There’s no need to take it off your wrist other than to charge it.
That’s enough to make me pre-order one but I appreciate you are probably a more discerning tech buyer than me so here are headlines followed by the details.
Assume these are all new compared to the 935
- Entirely re-vamped hardware – essentially a new watch that looks the same.
- Has PulseOx, like the MARQ
- Has Music, like the MARQ but 1,000 songs not 2,000
- Has Garmin PAY, like the MARQ
- Has Live Event Sharing, like the MARQ
- Has incident detection and assistance
- Has Body Battery Energy Monitor like the MARQ
- Has Heat & Altitude Acclimation like the MARQ
- Has training load focus like the MARQ
- Has Primary Benefit (Training Effect Labels) like the MARQ
- Has Round-Trip Creator (run/bike) like the MARQ
- Has Trendline Popularity Routing (run/bike) like the MARQ
- Has In-Workout Respiration Rate like the MARQ
- Has Around-Me ‘POI’ Mode like the MARQ
- Has Future Elevation Plot like the MARQ
- Has ClimbPro (more than Elevation Plot) like the MARQ
- Waterproof to 50m like the 935 but not as good as the 100m of the MARQ
- Also some ski and golf stuff (below)
- Has Advanced Vector Support…hmmm. I don’t know about that one !! (my brain is full of Garmin specs)
What’s New – Hardware Base
The new Forerunner 945 looks the same as the 935. But it’s faster and with more onboard memory, a new Sony GPS chip, Gorilla Glass and a new ELEVATE optical heart rate sensor. The 945 might LOOK the same as the 935 but really it’s kinda totally different inside! #Awesome
There are probably also new power-efficient components inside that we will never hear about but it’s the Sony GPS chip that WILL be the main contributor to boosting battery life just as the other features like music will degrade it. The new ELEVATE sensor might be a slight battery saver too. The bottom-line is that you now get a whopping 36 hours of GPS usage.
Note: Doubts exist about the accuracy of the Sony chip. Polar implemented new firmware yesterday from SONY that supports SBAS on the same chip that the 945 is using. My advice has always been to rely on a running footpod for pace/distance when running (I use STRYD) but that cycling speed and all post-workout tracks of where you have been will otherwise be accurate enough with the onboard GPS.
What’s New – Garmin PAY
Garmin PAY turns your watch into a contactless payment card. For your bank to work it absolutely MUST be on this list: link to garmin.com. In the UK I started a STARLING bank account just for these kinds of transactions as the per-transaction amount is limited.
What’s New – Music
The Forerunner 945 stores music onboard and plays it back over Bluetooth earbuds as you run. You can copy your personal music collection or sync from your SPOTIFY account, there are other providers too, but just realise that the Garmin Forerunner 945 doesn’t stream live. But that’s OK. I’m cool with all of that.
Neither Apple Music nor Google Play Music for now.
What’s New – Maps
Most of us will be Naysayers about the addition of maps.
Do we really navigate when cycling with a watch? Will we really use the inbuilt POIs to find a post-workout coffee shop? I suspect that as the months wear on and that part of your wrist that never gets tanned slightly adjusts to the 945’s shape then YES, I suspect you will start to do more of these things. Just because you can.
If you’ve never used Garmin’s on-device popularity routing then my recent experiences are generally very positive. It takes you where other runners and riders frequently go too.
Of course, a few of you will have been longing for maps for months for your sport-specific uses, so you’ll already be happy with this inclusion and reading the next section.
So, if you ever followed breadcrumb routes to navigate then it’s just made a whole lot easier with mapping and proper, re-routing functionality built-in. Indeed you can use the 945 just like a car’s satnav to find a route to wherever you are going and that place could even be a known POI. As Garmin’s maps gain more POIs then 3rd parties will be able to deliver interesting new location-based experiences for us via CIQ Apps
There are proper, routable onboard maps for the region in which you bought the 945. You can buy maps for other regions from Garmin and there are apparently free ways of getting them too.
You can also create routes on the 945 itself although the process is a little ‘clunky’ – personally, I’d stick to routes made elsewhere.
What’s New – Firmware
There are a few differences here but the meat of the firmware is broadly the same as the existing Fenix 5/plus/935 devices.
What’s New – Physiology by Firstbeat
Some of the calcs have been tweaked for more demanding environments and there are a few extra peripheral features that most of us will find occasionally interesting but which someone, somewhere will have a Eureka moment with.
- Heat Acclimation and Altitude Acclimatization
- 4 Week Training Load Balance/Focus
- Workout Labels
- Respiration Rate
- Training Status with Elevation/Heat factored into the calcs
- Training effect summary screen with numerical Training Load
- VO2 Max trend screen
- and the rest…
What’s New – In-Sport Features
For those of you who follow structured workouts from online providers, there are now improved ways for the likes of Training Peaks, Today’s Plan and Final Surge to natively get the files into the right part of your watch for you to use them.
The addition of ClimbPro is a nice-to-have. I’ve only really used ClimbPro when cycling, the wrist-format could work for fell runners who are following a specific race route but otherwise I’m not convinced about its real usefulness.
The new swim-run auto-transition feature for the MARQ appears to be missing. That’s strange but transition-related functionality WILL come to the 945 in due course (100% certainty).
So far so good. But here are the ‘feubles’ I’ve encountered.
- It took a long while to setup but that was more due to the fact there was more feature stuff to setup. It’s probably improved in reality over the 935, I guess, ie in the individual elements of setup.
- Manual music sync is super-slow from your personal collection. Like, sloooooow.
- Sound quality with my Jabra’s sounds alright. The 945 is only going to have an SBC codec so you can’t expect much more. But same as every other music-enabled watch but not as good quality as many smartphones.
- The buttons effectively stopped working and I got a replacement. The new ones are not brilliant
- There are some issues with CIQ stuff not being flagged as supported by the 945 (eg I think Humon Hex and also my favourite watch face). Consequently, you can’t use them (yet) Edit: now OK
- No-one has really mentioned the auto-elevation recalibration by GPS en route. Sounds nice. Doesn’t work too well.
- ELEVATE v3 and GPS…you can guess how good they are right? ….meh. Same old same old, no doubt other reviews will say how brilliant they are but you’re a clever lot so I won’t try to fool you. (Edit: actually there is a marginal improvement and swimming usage borders on vaguely acceptable…sometimes)
- I’ve got another SpO2 device right now and the 945 looks more correct than the other one (the other one tells me I am dead sometimes!…seriously)
- I can’t get the freakin’ thing to connect as a mass storage device by default. Always requires me to manually press a button, otherwise it connects like a smartphone with no drive letter assigned #PITA. I’ve had this problem since the 645 and yes I know there is a setting and that I can re-install USB drivers (doesn’t work)
- 945 is definitely faster than the 935, I would have preferred a bit more speediness. But it’s alright. #ModestImprovement #ABitSlicker. Edit seems to have got a bit slower over time already (6 months)
- Menus are pretty much the same and as complex as ever. Post-workout menu stuff IS better. My fave feature is bizarrely the Firstbeat workout label which really helps nail the classification of what you’ve just done and it matches how I felt. Or I could just trust how I felt in the first place 😉 Edit: addition of widget glances is sweet
- I can’t find the swimrun auto-sport change. Then again there’s quite a bit I can’t find on my 935 and I’ve had that 2 years 😉 (partly joking to make a point).
- Sometimes fails to pair or connect to ANT+ sensors. Requires the watch to restart. Grrrrr. Edit 6 months on and this STILL happens despite ANT+BLE supposed firmware improvements
- Battery life seems nowhere near that quoted. on the other hand i do have galileo enabled and listen to music quite a lot !! ie these are the battery eaters.
But it’s still a ‘happy camper 9/10 so far‘. Can’t wait for my proper GPS test but it’s down at about 5th on that list. Eesh.
Edit: I don’t regret buying the 945 in one sense….it’s got great smart features. In some ways, however, I regret buying it as a ‘just works’ sport-only device.
You won’t regret buying one, just the same old feubles will mildy annoy you. At least you can listen to music whilst being mildly annoyed and sit there super-smug with that coffee the 945 just bought you, as you know you have the best tri watch and no-one else does…yet.
Futures – What’s going to happen to the 945 over the next 2 years?
- I’m pretty sure we are going to see cleverer integration for TRAINING PLANS following the recent announcements of a TRAINING API. We shall see this more easily opening up Garmin devices to training plans from lots of new sources.
- We will also see quicker connectivity and connectivity to the more unusual devices.
- I think we will see moves to make more physiological and post-workout analysis even more accessible on the 945 itself to keep you in the Garmin ecosystem and stop you straying to 3rd party providers.
- We might see GOOGLE PLAY MUSIC as a CIQ Music provider and maybe even Apple Music too. Maybe. One day. Perhaps.
- There’s not too much scope to add new in-sport functionalities but we shall see more automation of transitions and more info about the mechanics WITHIN a transition (think about it), we will eventually see running with power properly integrated. But LATER rather than sooner.
“OK Garmin, take a lap” One day we will get voice activation of ‘sporty stuff’ but that will be the time when you know it’s right to find a new sport 😉
On that note. You already knew you were going to buy one. It’s now just a case of how soon you want it on your wrist.

The Garmin Forerunner 945 looks like the Forerunner 935 but is a wholly new piece of faster and more capable kit. The true ‘sport’ features have been tinkered with and improved a little but the main new features are the SMARTs coming from Garmin PAY, Music and Maps.
For once, it REALLY is a case that THE BEST has got better.
- Contains every ‘proper’ triathlon feature
- Revamped hardware – faster than the 935
- Great battery life for extended GPS usage
- Contains many new peripheral features notably ‘smarts’ like Maps, Music and Pay
- Awesome connectivity to external sensors and openness to 3rd party sites
- oHR and GPS accuracy need extended investigation (broadly OK)
- Menu interface feels clunky at first
- No FE-C connectivity but almost everything else can be connected.
- Don’t buy seocnd hand. Early units have button issues, tho most will have gone back to Garminand re-appear as refurb units.
