Yes, surely an interweb crucifixion. But hopefully also a yellow card. Regardless (or especially) if as some of you have speculated, the horse was somehow NQR it was her responsibility to feel that and make the best choice for her horse and that is what the yellow cards try to enforce.
However, the ground jury also have the ability to stop a horse on course and as well as the yellow card for her, hopefully there will be a full investigation as to why she wasn’t stopped when the horse was really struggling from a long way out.
For her, at least it was televised and she can watch it back and learn from it.
