Training load

Cairn computes the classic training-load model from your full activity history:

  • CTL (Chronic Training Load) — your fitness, a long exponentially-weighted average of daily load.
  • ATL (Acute Training Load) — your fatigue, a short average.
  • TSB (Training Stress Balance = CTL − ATL) — your form.

These are charted under Analysis.

Load is recomputed as a follow-up on every import, so adding or correcting a source updates your curves.
