I have many athletes who do this! We take two or three days off in a row if we need and count the week as recovery. I then plan all the build weeks around that. I usually suggest you get out and do an easy walk (20min) on the days you feel the worst. Getting your body moving does help even if it feels miserable in the moment. I wouldn’t take 7 days off, I would cut back the training like you would any recovery week but then take those days that are really hard as your days off and slowly build back into the week. Your rest week might not be a Monday-Sunday (as programmed) but rather a Thursday-Wednesday and that works great too!
Does that answer your question?
