Cycling Heart Rate Zones (Coggan)
Bike-specific zones from threshold HR — built on LTHR, not max, the way cycling actually trains.
Cycling anchors zones to *threshold* because HRmax is rarely reached on a bike and threshold is testable monthly without heroics. The 30-minute solo TT protocol (average of the final 20) deliberately underestimates a race-day threshold slightly — solo pacing honesty is the feature, not the bug.
