Going by past experience of the Manx, and taking into account last years itinerary, what with the many Parade Laps, Memorial Laps etc, I think  that the two races you are interested in, would probably be taking place on the:-

Monday: Newcomers Race

Wednesday: Junior MGP Race

as the Senior is always held on the Friday

However, I wouldn't bet on it, and unfortunately, we shall all just have to wait until the schedule is announced.
