Heart rate data field with heart rate zone colors and an estimate of fat and carbohydrate burned. DESCRIPTION HR Fat Carbs Color Field shows your heart rate so you can read it at a glance: the whole background lights up in the color of your current heart rate zone. On top of that, the field estimates how much fat and how many carbohydrates (carbs) you have burned so far – handy for planning your fueling on long rides. It shares its look with Power Color Field, Speed Color Field and Altitude Color Field, so all fields sit nicely side by side on one data screen. FEATURES • Large current heart rate with the background in 5 zone colors (white, blue, green, orange, red). Zones as on Strava: up to 65 / 81 / 89 / 97 % of max. HR. A small buffer at the zone boundaries prevents flickering. • Top row: carbs (blue) and fat (orange) burned in grams. Tap the field to switch between total carbs and average carbs per hour (dark blue, after the first minute). • Bottom row: calories and average heart rate (in its zone color). • Calories come straight from your Edge, so they match Garmin Connect. The field only splits them into fat and carbs by your intensity: plenty of fat when riding easy, almost only carbs at threshold. • Intensity from power and FTP with a power meter, otherwise from heart rate between resting HR and threshold HR. Short power meter dropouts (up to 10 s) are bridged. • Takes into account your metabolic type, nutrition before the ride, cadence and depleting glycogen stores on long rides (more fat after 1 hour). • Optional lab values (FatMax, max. fat oxidation, Fatmin from a gas exchange or INSCYD test): your measured fat oxidation curve then replaces the standard model. • In Garmin Connect: carbs and fat burned as charts plus the carbs burned for the whole ride. • Pauses: when the timer stops, the background turns light gray. • Crash-safe: if the field restarts during a ride, the totals continue. • Adapts automatically to any field size, from 1 to 10 fields per page. Labels are shortened step by step when space is tight. • English and German. SETUP 1. Install the data field and add it to a data page of your cycling profile: Activity profile › Data screens › select a field › Connect IQ › HR Fat Carbs Color Field. 2. Optionally open the settings in the Connect IQ app: – Top left: total carbs / carbs per hour (for devices without a touchscreen) – Max. heart rate (0 = from your Edge profile; enter your max. HR from Strava to get the same zones as on Strava) – FTP (0 = from your Edge profile, only needed with a power meter) – Metabolic type: more fat (endurance) / neutral / more carbs (sprinter) – Nutrition before the ride: normal / fasted or low-carb / carb loading – Threshold in % FTP (default 100) and threshold HR (0 = automatic, only without a power meter) – Lab values: FatMax (W), max. fat oxidation (g/min), Fatmin (W) 3. If your Edge profile has no heart rate zones and no max. HR is set, the field shows the assumed max. HR (190) for 5 seconds after the start as a hint. REQUIREMENTS • Heart rate sensor • Power meter optional (more accurate intensity) SUPPORTED DEVICES Edge 520 Plus, 530, 540, 550, 830, 840, 850, 1030, 1030 Plus, 1030 Bontrager, 1040, 1050, Explore 2, Edge MTB. NOTES • Fat and carbs burned are an estimate based on calories and intensity, not a measurement. Most accurate with a power meter and your own lab values. • The values in Garmin Connect only appear if the field is on a data page during the ride. • Privacy: the field sends no data. Permissions: recording (fat/carbs in the FIT file) and user profile (heart rate zones, resting HR and FTP).

VERSION 1.2.0 the text color now follows the same rule as in the other Color Fields (white on colored backgrounds, black only on white and light gray). The display stays the same. VERSION 1.1.4 - White text in zones 4 (orange) and 5 (red), also in the average HR pill, and the fat pill in red with white text: easier to read on the Edge. VERSION 1.1.3 - Updated heart rate zones: zone 1 up to 60%, zone 2 up to 70%, zone 3 up to 80%, zone 4 up to 90%, zone 5 above 90% of maximum heart rate. Colors: white, blue, green, orange and red. VERSION 1.1.2 - Larger pills and more readable labels in wide, shallow data fields. The main value adapts to the available space. VERSION 1.1.1 • Lap average HR: in workouts from Garmin Connect, the value now restarts with every workout step. VERSION 1.1.0 • New setting: heart rate in % of max. HR. The main number and average HR are then shown as a percentage of your max. HR instead of bpm. • New setting: average HR of the current lap at the bottom right (ØLAP) instead of the whole ride; it continues after the field restarts. • Italian translation. VERSION 1.0.2 • Lower battery use: less work when redrawing, crash protection saves every 5 minutes instead of every minute (pause and stop still save immediately). VERSION 1.0.1 • Fat burned for the whole ride as a total in Garmin Connect (previously only as a chart). • More robust start: if the Edge cannot set up recording at power-on, the field keeps running anyway. VERSION 1.0.0 – First release • Heart rate in 5 zone colors as on Strava. • Estimate of fat and carbs burned from your Edge's calories, carbs as a total or per hour. • With or without a power meter, optionally with your own lab values (FatMax, max. fat oxidation, Fatmin). • Carbs and fat burned as charts in Garmin Connect.
