GC HeartZones Accumulation

Track exactly how much time you spend in each heart rate zone, right on your Edge screen. GC HeartZones Accumulation displays a live bar chart of your accumulated zone time during a ride — one bar per zone, growing in real time as you ride. The current zone is highlighted with a border, and a subtle arrow appears when you're within 5 bpm of crossing a boundary, so you always know which way you're trending. **Features:** - 5-zone bar chart with per-zone minute counters - Live zone indicator with boundary proximity arrows - 10-second progress segments within each bar - Zone ranges shown below each bar - Colour-coded by zone (blue → green → yellow → orange → red) - Automatically loads your biking HR zones from Garmin Connect, falling back to generic zones or estimated max HR if not configured - Resets cleanly on activity start; pausing freezes accumulation
