Rivers run fastest in the narrows. Pressure speeds you up, and it can also wear you out.

Pressure does two things at once, and people usually only mention the first. Water in a narrow channel speeds up, which is why constraint can make you sharper and faster than you have ever been, and the same squeeze is grinding at the banks the whole time. Both are happening in a hard season. The performance is real and so is the erosion, and you will notice one of them much sooner than the other.

If you are in the narrows now, schedule the recovery rather than hoping for it. One real day off inside the next two weeks.
