In an interview in 2002 she said Cadel Evans, was a role model: "I've been following his progress and looking up to him since my early days. He's definitely a bit of an inspiration!" On whether she would make the transition to road racing she elaborated "I don't know if I could swap over like Cadel Evans has done, but it's something to think about."
