I have the exact same predicament! I want to follow the TR plan as closely as possible but want to retain the social aspect of cycling also so would like to keep up my Sat Club rides. Last sat rdie alone was 431 TSS so it is a sizeable chunk. I’m guessing I will perhaps reduce the Sun workout to esnure recovery and will do the usuall Mon-Wed workouts as planned.
it does make the overall TSS for the week seem excessive vs what is planned but I will just evaluate as the plan goes over the coming weeks.
Thanks for all the input guys!
