EnduroMetrics Cycle
· vv1.1.6
About
A complete endurance training dashboard that brings all critical performance metrics into a single screen:
• 2 key thresholds: LTHR, FTP
• 7 color-coded zones for Heart Rate and Power
• 2 low-value transition zones (avoid)
• Fully aligned with polarized training models (Dr. Stephen Seiler)
• dEF™ (Dynamic Efficiency Factor) for real-time performance & fatigue control
• Ride Stress Score (RSS) in real time (TSS-like)
• 6 metabolic fuel zones: Base, Fat, Balance, Glycolysis, Carb, Over
• Fat & Carb Burner shown in real grams
Same thresholds. Same colors. One goal:
to know if your training is actually working.
________________________________________
During a workout, what do you really watch?
Heart rate or power?
And which one is actually leading?
If Power is correct but heart rate keeps rising — do you continue?
If heart rate looks fine but performance drops — do you push?
Are you in the right zone, for the right reason?
Garmin shows you data.
EnduroMetrics-Cycle shows you how to read them together — in real time.

Triangulation Protocol™
Every workout has cost and output.
The mistake starts when you look at only one.
EnduroMetrics-Cycle is built on three anchors:
• Effort: Heart Rate relative to LTHR
• Performance: Power (FTP)
• Control (dEF™): real-time control of performance relative to fatigue
Two thresholds. One performance control.
________________________________________
What leads each workout type
Long Ride/ Recovery / Aerobic Base
• Effort leads
• Heart rate defines intensity
• If dEF™ drops → reduce intensity
Tempo / Threshold / VO₂max / Intervals
• Performance leads
• Follow power
• If dEF™ falls below ~0.93 → reduce intensity
Performance is becoming too costly.
________________________________________
How to read it on the watch
• Top bar: Effort (HR vs LTHR)
• Bottom bar: Performance (Power vs FTP)
• dEF™: performance & fatigue control
One glance tells you what is leading.
________________________________________
Zones without dead spots
Same colors for HR and Power.
• 5 productive zones
• 2 low-value transition zones
Transition zones (TL & TH) do not build endurance.
They only increase fatigue.
________________________________________
Support metrics
Live Fuel Mix
• 6 metabolic zones
• Fat & Carb Burner in grams
dEF™
• Central control of performance and fatigue
• Automatic cardiac drift detection
RSS (TSS-Like)
• Real-time training stress
(1h at Threshold = 100 | 1h Zone 2 ≈ 60)
All metrics are recorded in the activity file.
________________________________________
From watch to training plan
Same thresholds and color logic across EnduroMetrics. The free Formula Generator helps you build structured workouts, while the data field works with any training plan coach-made, self-built, or third-party giving real-time control of intensity and efficiency.

Who it’s for
For cyclists who don’t want more numbers.
They want to know if their training is working.
EnduroMetrics-Cycle
Train by two thresholds.
Evaluate by efficiency.
Adapt in the right zone.
Set LTHR, FTP
For the first time, your data makes sense.

Version v1.1.6
• Smoothed power (3s) for a more stable and readable UI.
• dEF optimized for consistent values across endurance sports.
• Zone 1 HR (LTHR) and power (FTP) ranges expanded downward to better capture very easy efforts and relaxed sessions.
• Wider HR and power zone lower bounds for improved stability at low effort.
• Added a 20-second initialization guard at workout start to stabilize sensor data before dEF calculation.
• Displayed the active EnduroMetrics version on screen.
• Improved dEF stability and accuracy during interval-based workouts.
New Version Release v1.1.5
Performance & Accuracy Update
Scientific RSS (Running Stress Score) Calculation
• RSS now uses the formula IF² for accurate stress scoring
• 1 hour at Threshold = 100 RSS
• 1 hour in Zone 2 ≈ 60 RSS
• Fully aligned with Garmin training standards
New RSS Metrics Clarification...Real-time, TSS -equivalent training stress score, non-linearly weighted to reflect harder efforts, using power (performanceRSS) and heart-rate (effortRSS) analysis
• hrRSS has been renamed to effortRSS
– Represents cardiovascular stress based on heart rate
• wattRSS has been renamed to performanceRSS
– Represents mechanical and muscular stress based on power output
This separation allows athletes to clearly understand:
• How much stress the heart experienced (effortRSS)
• How much stress was generated by legs and power output (performanceRSS)
• Applicable across all supported activities
Improved Accuracy
• Macro calculations upgraded to 3-decimal precision to eliminate cumulative errors and optimized formula for better accuracy
