The blurb says only, “Primary coaches of an athlete assigned to a Grand Prix Series event are required to attend.”

Interestingly, there’s a JGP (Slovakia) scheduled Aug 22-25, which means it overlaps with 2 days of Champs Camp. So if, for example, Jun Hwan Cha or Steven Gogolev (I think Brian is primary for both) compete there, Brian almost certainly won’t be at Champs Camp. Which begs the question of who will, because if you recall, Brian said that he and Tracy would be Jason’s head coaches “on paper,” but Karen Preston and Lee Barkell would also work with him.
I guess who goes to Champs Camp may signal who he’s working with the most (or is most comfortable with). I’m wondering if it might be Tracy, or perhaps Karen Preston - I think she used to coach in US, and may have dual citizenship - but since training clips we’ve seen don’t show his individual training, it’s hard to say. Anyway, I guess we’ll see.
Last but not least: it looks like he’s not absolutely required to attend one of Glacier Falls, Skate Detroit, or Philly, but will he? I guess Philly is most likely?
