It's a tough one to call right now. Page seems to coming into form just at the right time. My vote is Trebon. He hasn't been as consistent this year, but I think he'll come good in the big race.
It seems like Katie Compton has been taking lots of time off racing. I think she's prime for a top result at Worlds. I'm also excited to see how the U23 guys peform. There's lots of hype around Summerhill. We'll see how he does on center stage.
