For me, triathlons were something that was down to me and my fitness. Now, I really enjoy the pain in the triathlon of chasing someone down. It's a bit like chasing down Nico Rosberg in the last few laps at Silverstone - it makes you feel alive.

To understand the intensity of driving an F1 car, you have to be in it. When you're driving a 750hp machine at 320km/h, the noise and the vibrations are incredible. The G-force when you take big corners is like someone trying to rip your head off. You hit the brakes, and it feels as if the skin is being pulled off your body.

I need to develop a car and engineer a car in a position that feels comfortable for me, and I don't think anyone can do a better job than I can in that position. The problem for me is if I can't get the car there I do struggle more than some.

I always sleep really well, particularly before a race, when the adrenaline's pumping.

It doesn't matter who wins if I don't. I only care if I win. I'm jealous of anyone else who wins.

I like old tunes when I'm driving. They're fun and uplifting. Billy Ocean, that kind of thing.

Women don't get the same opportunities that men get in racing, so they don't get to learn race craft.
