Main versions
This manual covers the 4 main versions of Datarun premium, varying in number of metrics on screen
from 4 to 7. It also covers the copy versions.
The location of the main versions in the Garmin app store:

You need a license for each of these 4 main versions; see the last part of this manual.
Copy versions
Per main version I have also made copy versions. If you have a license for a main version of Datarun
premium with 4, 5, 6 or 7 metrics, you will be enabled to generate a license key for copy versions for
that specific main version (see the last part of this manual). The advantage of having copy versions is
that one can have more than one sets of setting. Also I have used the copy versions to deviate a bit in

Summary of Contents for Garmin Datarun Premium FR645

  • Page 1: Table Of Contents

    This manual covers the 4 main versions of Datarun premium, varying in number of metrics on screen from 4 to 7. It also covers the copy versions. The location of the main versions in the Garmin app store:  4 metrics: https://apps.garmin.com/nl-NL/apps/76af5825-6594-4337-8a8e-82193a47ed12 ...
  • Page 2 This was needed because of a flaw in the Garmin ecosystem; although I have made the code modular and watches with 32 kB available for datafields don’t use or see the extra code for the 128 kB-watches, the extra weight of the larger settings file is getting the memory of the 32 kB-watches overloaded.

  • Page 6 The heartrate zones are taken from your Garmin account settings. The label colors are however not the colors you see in Garmin connect. Also for cadence the label coloring is different, though the cadence zones are identical to what Garmin uses Pace and averaged pace can be round off to 5 seconds per mile/km (like 4:05 or 4:10) The battery becomes red if power gets below 15%.
  • Page 7: Remarks About The Options

    Remarks about the options Altitude, elevation gain and elevation loss Elevation gain and loss are Garmin's internal values that the watch calculates itself ànd come in feet or meters depending on watch settings. Altitude is also in feet or meters depending on watch settings.
  • Page 8 183-300=red. Heartrate zone coloring This is only available for the FR645m, the Fenix 5x and the Fenix 5 plus series. The Garmin color scheme is: zone1=grey, zone2=blue, zone3=green, zone4=orange, zone5=red. Although this range is logical for Garmin connect, from grey/blue to red based on the intensity of the run, it visually is less workable when running.
  • Page 9 10. you need to have de Stryd datafield active on a 2 datafield-screen in order to get all the power and other metrics recorded into the fit file and synced to the Garmin website and the Stryd powercenter Garmin power is not supported. Garmin choose not to implement native power or do a hack that supplies the Garmin power to the channel that receives power meter data.
  • Page 10 Normalized power This is only available for the Fenix 5x and the Fenix 5 plus series. I included Normalized power as people kept asking for it, but wasn’t sure what the use was during an activity. Coach Steve Palladino however explained it in a post the Stryd Facebook page: Normalized power is a metric that was developed out of necessity for cycling power analysis and interpretation, because cycling power output can be quite variable.
  • Page 11 An increase in value shows increased endurance, see https://www.trainingpeaks.com/blog/how-to- use-aerobic-decoupling/ for some reading. Training effect Training effect is a metric developed by Firstbeat and licensed by Garmin. On this page you can find more info and a whitepaper: https://www.firstbeat.com/en/science-and-physiology/epoc-and- training-effect/ Lap pace and structured workouts Since the summer of 2018 lap pace and other lap related metrics are working for automated laps, produced by a structured workout step (thanks to the CIQ3-firmware update by Garmin).

  • Page 13: Installing And Using The Datafield

    Don't forget to specify the options you want in the settings, otherwise you get the default settings that I have specified. You can change the settings through the Garmin connect app, but for some people that doesn't work. Connecting to a PC and using Garmin express always works for changing the settings.
  • Page 14 When you are ready to order a license, you can use the setting "Show demo field for ID's and check license" in Garmin Express/Garmin Connect to get the ID's shown directly. The other option is to start an activity and wait for 15 minutes of activity before the "License needed"...
  • Page 15: Creating A License Key For A Copy Version

    The license must also be given in in the settings through Garmin Express/Garmin Connect (preferably Garmin Express on the PC/Mac). You can check whether the watch recognizes the license, by using the "Show demo field for ID's and check license" setting again.
