Hi Joan,
Lynda is out on sabbatical until June. I don’t know the exact details of the plans, but in general yes. You’d want to make the Thu workout (and Sat workout for Sunday races) lighter, and modify the few days after the event to include more recovery as needed. Let perceived exertion be your guide.
There are different situations. If you have a race more or less than 40 miles, you’ll want to modify the recovery post-race as needed. Keep the lead in to the race the same.
Another is where the race falls in your program. If it’s a rest week you may not need any changes.
