There are many different views on tapering. How long should the taper period be? Should you reduced volume, speed or both - or should certain sessions be replaced with others? There are no easy answers.
A recent https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10171681/ looked at various studies and suggests that a pre-taper over-load before a shorter taper can work well. https://www.frontiersin.org/journals/sports-and-active-living/articles/10.3389/fspor.2021.735220/full suggest a structured 3-week taper is best.
Dad and George discuss detraining and how their training (high mileage) and continual predicted improvement strategy might favour a shorter and less intense taper.
George also talks about her sensible 'carbo-loading' approach.
