Yes, I've already seen from Ritz and Nelson that neither is all that happy with their results, though Nelson seems to be saying not all he hoped for but still a good debut. I'd also assume Torres isn't thrilled with his run, though I haven't seen anything from him on how he felt about it.
Saw something from Bairu that makes it sound like he blacked out. He sounds confident about avenging this disappointment, saying he recalls finishing near last at his first World Cross before running much better in his second World Cross race.
Meb sounded a bit disappointed in not making a different tactical choice mid-race when the race broke open but still very happy with his overall performance.
