Fitness (CTL)

TrainingPeaks represents Fitness (CTL) in blue font and the blue line (in the Performance Management Chart) through the TrainingPeaks ecosystem.

What is Fitness (CTL)

Chronic Training Load (Fitness) combines duration and intensity to provide a value of how much an athlete has trained historically. TrainingPeaks calculates CTL, by default, as the exponentially weighted average of daily TSS for the past 42 days (7 weeks). Note that, in effect, CTL represents the training an athlete has done in the past 3 months given the nature of exponentially weighted averages. 

Formula

CTLtoday = CTLyesterday + (TSStoday - CTLyesterday)(1/CTL time constant)
