Reduce instead of catch up
Missed workouts do not create a debt that must be repaid right before a race.
Keep a few familiar cues
Reducing load does not necessarily mean stopping completely; the goal is to arrive fresher.
Do not judge fitness from one day
Feelings can vary during a taper. One heavy day does not erase the preceding weeks.
Takeaway
Test changes in training, adjust gradually and do not turn general information into personal diagnosis.
