A slew of software updates coming to Garmin Forerunner 945, 745 & 245

Good news for owners of Garmin Forerunner 945, 745 and 245. The trio is getting a long awaited, hefty software update. This is available for all in Beta. The public release should follow soon.


Main updates

  • More accurate sleep tracking: coming to owners of Forerunner 745 and 945 watches. These are more accurate sleep tracking statistics and a sleep widget that utilises Firstbeat algorithms. The feature was introduced on the Fenix 6 nearly a year ago and has made their way to Garmin’s recent watches (Enduro and Venu 2).
  • Trail Run VO2Max – this was originally introduced on Enduro and slapped onto Fenix 6 as a software update. It it is a slightly tweaked version of Garmin’s VO2 max which tracks your cardiovascular fitness level and adjusts based on trail conditions. The hope was the feature would trickle down to other watches. Now it has to Garmin Forerunner 245/745/945.
  • Better Body Battery metrics – a recent update to Garmin’s algorithms, up to now Venu 2 was the only watch with the improved stats. The changes put more emphasis on sleep when calculating Body Battery. So if you want to bump up the metric, make sure to get enough kip time. Hopefully, the tweak will help make the figure more representative of your actual state. Available for 245/745/945.
  • Perceived effort: The new prompt appears when you save a workout. You’ll need to enable it by going to [Activity] Settings > Self Evaluation for options. Basically, before saving the activity you’ll be asked to grade your effort on a rotary dial that goes from zero to 10. The metric will then appear in your exercise stats.
  • Ultra Run activity profile: Available on Enduro and Fenix 6, the activity profile is coming to the Forerunner 745 and 945.
  • Daily Suggested Workouts: The 245 is getting workout recommendations based on your sleep and wellness data.
