Roxy, I wouldn’t be quite that harsh. I don’t entirely disagree with your assessment of the errors, but you make it sound like she lacked the skills to be there at all.
Rather, I saw a rider relatively new to 1.6m, the international stage … at Aachen. Lack of experience and a whopping case of nerves can account for mistakes we wouldn’t otherwise make at home capably riding the same height/degree of technicality. Very few of us are fortunate enough to move up seamlessly and without disruption. Most people I know marvel at how awful their first few rounds are when the move up. It’s like you wonder who was in the ring that day because it couldn’t have been you. “You” haven’t done stuff that stupid in years!
She was far from awful, and because she is a good rider with a freakishly talented horse, she ended up 2nd to Big Star. Any other horse and it would have been an 8 fault first round, welcome to the big time day that most riders experience (and are thrilled with) when they move up.
