Rest is a dose. Stopping is a decision. 🛑
There is a difference between the two, and it costs riders more than any training error we see at this time of year.
A rest week is prescribed. It has a start, an end and a purpose, and the fitness it protects is still there on the other side. Stopping has none of those things. It begins with a wet Tuesday and a good reason, and it tends to be discovered retrospectively - usually in November, usually while looking at a power file.
The physiology does not punish you for the first one. Blood volume and stroke volume, the first things to go, fall over weeks rather than days, and the muscle adaptations underneath hold far longer - Coyle's athletes still had capillaries and enzymes 50% above untrained after twelve weeks off. Ten days at the end of a hard season costs very little.
What it punishes is the version with no end date. Nine to twelve percent of your blood volume inside a month (Codella et al., 2024), stroke volume following it down, and a summer's delivery system quietly coming apart.
So take the rest. Just decide when it finishes before it starts.
