Zara To Miss Olympics Ceremony
Zara Phillips has admitted her mum and dad haven't said much to her about their Olympic experiences.
The Queen's granddaughter has been talking in Greenwich for the first time since being selected for the GB eventing team next month at the London Games.
But she's told London's Heart she has the support of Princess Anne and Mark Phillips.
"Obviously very proud and you know behind me all the way. I wouldn't be here without them anyway. Its great that I've been able to be selected but we've still got to get there and we're working really hard."
The 31 year old will ride High Kingdom at Greenwich Park in London next month and won't go to the opening ceremony as the competition starts the following day.
And Zara says she's hoping for more luck than the Princess Royal. "Mum fell off and I don't think my Dad ran the cross country" even though her father won team gold in 1972 and silver in 1988.
"He's not a big talker, he's more interested in training, I think it comes across that way. But anyone who's picked for the Olympics it's a massive honour."
Zara's part of the five strong GB eventing team that also includes Kristina Cook, William Fox-Pitt, Georgina French and Mary King.
