Power curve: fresh vs fatigued

How Your Power Drops as the Ride Goes On

Your best power at each duration, measured at different points in the ride

kJ Fatigue Curve

Cadence vs Fatigue

Cadence at matched power band across cumulative work — no altitude filtering available

Aerobic Efficiency Trend

Watts per heartbeat across cumulative work — flat = durable, declining = fading

Estimated Fuel Burn

Supplementary Metrics

These metrics are influenced by ride type, pacing strategy, and terrain. Use with coaching context.

HR Drift
--
bpm/hr
Heart rate drift per hour — lower is better
Durability Index
--
%
NP ratio (last 25% / first 25%) — affected by race pacing
Power Fade
--
W
Half-split NP difference — less meaningful for interval rides
