What does the TR bible say about doing two workouts on the same day?
Is it the same principle as during a strength training phase, AM weights + PM bike; hard days hard, easy days easy, kind of thing…or are double bike workouts a different creature altogether?
Is there an advisable ‘block’ duration. e.g. do 1/week for unlimited weeks; do 3/week for 2 weeks, etc.? Could you essentially do a week of training in three days?
How would the TSS for double workout days differ from doing two single workout days, e.g. 1x220 TSS vs 2x110 TSS?
Appreciate any literature, links, podcasts, resources, etc.
