Run — half-marathon prep + efficiency
Run Pace by HR Zone (weighted-median pace at each HR zone — fitness ↑ when lines drift up)
Smoothing scalar:
Run Efficiency (HR ÷ GAP-mph — lower = fitter)
Aerobic Durability (decoupling % on long runs ≥75min — lower = better fade resistance)
Run Zone Distribution (monthly hours per HR zone — runs only)
Weekly Run Volume (total miles & hours per week — base building)
Ride — century prep + efficiency
Ride Power by HR Zone (weighted-median watts at each HR zone — fitness ↑ when lines drift up)
Smoothing scalar:
Aerobic Durability Trend (trailing-90d median decoupling % on rides ≥2hr — lower over time = better)
Ride Aerobic Efficiency (HR÷W within each HR zone — lower = fitter)
HR-Zone Distribution (rides only — monthly hours per HR zone)
