Garmin Forerunner 945 – new firmware

There’s a big chunk of new features in the 945‘s firmware that are available now, here. Most notably is the addition of DAILY SUGGESTED WORKOUTS and TRACK RUN. We saw the former for the first time a few months ago in the Garmin Edge 1030 Plus and I checked out the TRACK RUN mode in the Garmin Forerunner 745 (the smaller, non-PRO 945) last week. These are significant and useful sporty features.

I was also intrigued by the line for “Improved optical heart rate performance.”. I am a bad physiological candidate for oHR and often get bad readings however the current generation of Garmin ELEVATE is probably the best oHR tech, at least as far as my own experience goes. That said, the Apple Watch 6 is perhaps offering ME (just me, you could be different) possibly better results. I used to base all my training load data solely off HR and so people in that same situation might well start to consider watches like Apple Watch if they can more reliably produce more accurate HR stats. So that’s a warning shot across Garmin’s bows and maybe this mysterious new firmware addition for the 945‘s oHR sensor will deliver some notable improvements? Probably not.

Recovery Time is also improved. I DO look at recovery time and consider what Garmin is telling me here. I suspect that what Garmin has introduced are subtle algorithm changes that will still keep the initial recovery time the same but shorten it if your recovery goes well. This would be sensible and will help some of you but, for me, it wouldn’t help as I VERY RARELY consider the remaining recovery time ie I remember what it says at the end of a workout but never return to look at the number of remaining hours until full recovery. Having said that, one day’s recovery (or lack of it) will impact on recovery after the next day’s sessions so, thinking about it, it WILL probably help me too 😉

Daily Suggested workouts is a very nice feature. It’s great in principle and the recommendations look vaguely sensible to me, although they do seem to recommend BASE work too much for my liking. Even at a simple level, it’s sometimes nice to just ‘do something different’ and so why not do what Garmin says from time-to-time? Even if Garmin’s suggested workouts are not the absolute precise optimal recommendation, chances are they will be vaguely appropriate.

  1. Just to make sure – if my nearby track isn’t 400m, but for example 260, then this track feature is useless for me?

  2. I thought they’d have left these ‘new’ features for the next gen of forerunner 900 family. I ‘m really curious about what a 955/fenix 7 will add other than LTE (maybe)

      1. Really? But it should come in a future version, right?
        I think Ray said something similar around 745, the remove sleep tracking on the watch in the release version of the 745 (and Garmin should update in some weeks)

        BR

  3. The updated recovery algorithm will extend your times as well based on stress. I know because last night my 945 (on this beta FW) told me my recovery time with the note “Delayed by High Stress” below it. I feel like I’m being judged by my watch. I regularly have high stress readings (according to Garmin; I feel fine, but maybe I’m just accustomed to it now), so I expect to see that note a LOT moving forward.

  4. I updated last night but can’t find the Track Run under activities on 945. Any pointers? Also i can’t seem to find the Suggested WO.

    1. i don’t specifically test that. however, I do know when i get very annoyed that there’s no power
      with the 745 (or any new device) I specifically avoid adding anything unnecessary…so that’s stryd+pm+hrm and one ciq field. i have lost power a couple of times and coincidentally was perilously low today before i headed off.

      the 745 definitely has me skirting more frequently with battery death. that said devices like the 945 have got me used to charging less frequently so i would have been treating the 745 on a similar basis, which would be UNfair

      to answer your question: it’s supposed to have been improved. i hadn’t especially noticed.

      1. Ah ty, nice to know. I just tried again and i am still on 5.00. (location germany). Maybe it needs a couple of days.

  5. Ive got FR945 and Edge 830 what do you think how Garmin will solve sychro between those two devices, when FR get different recovery algorim?
