"It is also a Christian uni and I am member of the Church of Jesus Christ of Latter-day Saints myself. BYU has different standards and even an honour code, so by deciding for them, I hope to get away from peer pressure as well," Krystie says.
Although she says she loves New Zealand and training in Hamilton, Krystie thinks going to the US would get her out of her comfort zone. "I want to be the best runner, but also the best person I can be. And it will be good having some independence," she says.
Sacred Heart Girls' College principal Catherine Gunn says: "I have every confidence that Krystie will be competing on the world stage. Her dedication and determination to succeed as a young athlete is inspiring and she sustains exceptional standards in all her academic endeavours."
Krystie finished school in December. Now she is trying to find a job and save some money for her big trip. "And I am studying for my SATs that I have to sit before going over."
