Are show schedules affected by the marathon?

So I got TKTS vouchers for Christmas last year that I have not yet used, and they expire at the end of the year. After some finagling with schedules, the only time that I can meet with the people I was intending to use them with is tomorrow, which is the day of the marathon.

We can figure it out transportation-wise, but I cannot find any information on whether or not the regular Sunday matinee schedules for Broadway shows are affected. Does anyone know?

Thanks all! Looking at the route, I figured there wouldn't be an issue but wanted to check to be sure.
