The event was to be held at the Peelbergen International Equestrian Centre in the Netherlands, with Adele jumping 1.20m - 1.30m on a borrowed horse. She was part of a 10-person team from New Zealand organised by Jacob Thompson, competing with teams of young riders from all over the globe.
Departure date was April 10, returning on April 24, but that has now been postponed until next year.
Part of the attraction for Adele was the training she was to receive before the event.
"I hoped that I would have gained a lot of skills and training techniques to apply to my horses at home," she said.
In the meantime Adele had combined her studies with showjumping, coming 4th in the Horse of the Year 1.10m-1.20m event in a huge field and finishing in the top half of the Junior Rider competition won by Samantha Carrington.
