Yes, I have spoken to a number of skaters who have had no help from their respective federations, even to go to Senior worlds. But it's also their only chance to compete at that level, so it's a trade off. One that many skaters and their parents feel is worth it.
Yes I was surprised to see a crowfunding for Zoe Jones & Christopher Boyadji to go to Worlds... Airplane from UK to Finland can be cheap and hotel may be not too expensive too... Maybe I'm a bit optimistic with the money a federation have, but I imagine that to send skaters to Worlds could be a priority?
