Routine during the week of a race

Doing a race in a week and was hoping to get some advice from some more experienced runnings to see what their routine is during the week leading up to it. I want run more this week to prepare cardio wise but I dont want to get burnt out. Do yall go light during the days leading up to the race? Do you rest the day before the race? Do you start carb loading days before? Any advice on this topic is appreciated.
