Whether I'm 70 or 30 in the world, it really doesn't matter.

My mum and dad are both sportspeople and know what's it all about. They know it's hard work, but they also know what it takes to become a professional athlete. I don't think - without their help, I wouldn't have got this far.

Reaching my first grand slam final was amazing, and I didn't expect it at just 19 years old.

I like playing at the U.S. Open because I like New York. It's a nice city. You can do anything there. It's one of my favourite cities in the world. I also like Indian Wells and Miami, too.

I think everyone wants to look good whether that's on the court or off the court.

I'm so happy to have done this, and now I can say I ran the New York City Marathon.

Every time I go out onto a tennis court, I know what to expect.

When I said I wanted to run a marathon, I wanted to do it under four hours. But when I started training, I was like, 'Oh I got this,' so I wanted to run between 3:30 and 3:35. I'm really proud of myself.

I give 110 per cent all the time.

Wimbledon is very special with the traditions and everything.
