I fly quite a bit on business in Europe and it can be quite problematic, delays and cancellations are common. To avoid these issues, I always aim to get to a client meeting in the night before the flight. This is not an option here as her race on the night before is quite late, 9:40pm (I think). So, being driven and sleeping at night, getting to a hotel and sleeping some more in the morning, with some warm up in the afternoon prior to the second race sounds reasonable to me.
Btw, I doubt she would fly first class...
