Creating this data field was inspired by the "80/20 Training System"*. The data field gives a visual feedback about the training zone you're currently running at. This helps to plan and train more effectively as you won't have to tinker with the training zones of your watch. The zones are labeled as specified by the "80/20 Training System". You will get a detailed summary after your training in Garmin Connect. So you can reflect training goals and plan your further training accordingly. You can switch display from heart rate, pace or power by pressing start/stop twice during activity. Please set up your lactate threshold heart rate, functional training pace and power in the ConnectIQ app settings to get correct zone calculation. Instructions about finding these values can be found in the book mentioned below or at www.8020endurance.com. The zones are then calculated automatically. Note that data for all three types of metric will be recorded and will be displayed later in your training statistics on the Garmin Connect platform! NOTES FOR USING POWER SENSOR: - Enter STRYD power sensor ANT+ ID in app settings for direct connection to sensor. Enter "0" for ANT+ ID to use power sensor connection from watch (default). - Remove ANT+ ID string in app settings to not display and record power at all. ------------------------------------------------------------------------------------------------------------- * The "80/20 Training System" was invented by D. Warden and M. Fitzgerald (www.8020endurance.com) and zone calculation algorithm is based on their book "80/20 Triathlon: Discover the Breakthrough Elite-Training Formula for Ultimate Fitness and Performance at All Levels, 1. Ed, 2018, DaCapoPress, NY". The app was approved and created with the kind support of the authors. The logos are copyright by the authors. All rights reserved.

V6.0.1: - added option for slope adjusted pace calculation - using Connect SDK 9.1.0 from 05/2026 V3.1.2: - using Connect SDK 8.2.1 from 2025/06 - new watches Forerunner 970, 570, Venu 1x V3.0.0: - Enter STRYD power sensor ANT+ ID in app settings for direct connection to sensor (fix for GARMIN watch using GARMIN run dynamics power data instead of STRYD sensor data). - Enter "0" for ANT+ ID to use power sensor connection from watch (default). - Remove ANT+ ID string in app settings to not display power at all (only shows pace and heart rate then). - Switched to API Level 3.1.0. For older watches like Fenix 5, Forerunner 245, etc. please use 80/20 Run Zones (Version 2) or 80/20 Power Zones datafield. V2.6.0: - added workout display when using Garmin Connect Workouts. Workout notes and count down timer will be shown in lower section of fullscreen mode. V2.5.1: - added overview screen when starting in fullscreen mode V2.4.6: - added new devices V2.3.1: - update for latest watches V2.2.1: - additional setting for averaging pace data V2.1.1: - changed layout for round displays (low/high letters now below time/percentage) - added new Garmin devices V2.0.0: - added dual data screen (can be activated in Connect App/Garmin Express) V1.9.x: - added super small bar display for more information even when using in combination with 3 or more datafields - optimized full screen layouts for Garmin Venu, Forerunner 735XT and others V1.8.x: - new option allows to change metrics from the watch by pressing stop/start during activity (must be enabled in app settings!) - power averaging can be increased up to 30s mean value - background color can be set to "Default" in order to use the preset background color of your watch V1.7.3: - added "low-high-summary" to pause screen, remove lap display from fullscreen - changed color of "Zone.Y" to orange - improved screen layout for minimal view - improved minimal view (shows "+/- Zone" when above/below zone goal; shows summary when paused/stopped) V1.6.3: - added Garmin MARQ series to list of supported devices - vibration alarm when zone increases/decreases (can be activated/disabled from app settings!) V1.5.0: - added Garmin Venu to supported devices - power data now also shown in 3rd party apps (TrainingPeaks, PerfectPace, Strava, ...) V1.4.0: - adjustable moving average (1-10 seconds) for power smoothing V1.3.0: - added optional switch to show overall percentage in low and high zones instead of time - added optional switch to take LTHR from user profile instead of adjusting it in app settings (make sure heartrate setting is based on lactate not on max. heartrate!) V1.2.0: - background color adjustable (black/white) - half screen mode shows data, zone and range V1.1.4: - added Descent MK1 watch V1.1.3: - functional threshold pace can be entered with leading zero or without in app settings (i.e. "8:32" or "08:32", not adding a zero caused wrong zone calculation before!) - removed calculating 3 seconds mean value for heart rate (as heart rate changes very slowly I don't think this is necessary) V1.1.2: - modified data field to be compatible with watches of API level 2.4.x (i. e. Forerunner 735XT); separate version for older devices like Fenix 3 can be found here: https://apps.garmin.com/en-EN/apps/827c257e-4b24-4099-b6c5-84227f926ef9 V1.1.0: - pace automatically shown in miles/hour when imperial units selected in system menu - label "none" replaced with "below Z1" - counting HR time as low intensity also when in Zone "below Z1" in regards to cardiac drift
