She needs to be in far better shape if she's going to enjoy this kind of ride.
I'm always in reasonable shape, but not always in top cycling shape when I start a tour. Even when I'm in really good shape, the first three days are usually hard. By the fourth day I get in the groove and can do some miles.
I suggest you plan a route with easy days at first. I like 25-30 the first day, and 30-40 the next two days.
