When it comes to my racing career I'm very driven and very selfish. People who are around me at races will know that I'm a different person here than in my personal life. I completely blank people at races. I need to be focused. I'm rude.

I think as a 20-year-old you expect life to always be easy. You get given a good hand and the chance to race in Formula One. You think the driver can make the difference, can make up for everything else within the team. But that is not the case. You are racing in such a competitive sport so that doesn't happen.

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.

It is such a special feeling to win a grand prix.

I don't purposely speed, but I might go over by five or six miles an hour from time to time. It doesn't give me a buzz driving on normal roads, because I can't go fast enough. It's never going to be anything like an F1 car.

To drive an F1 car you have to be a little mad. On the morning of a race there's a mix of excitement and fear. If it's a wet track, then it's worse as you're not in control most of the time, which is the thing all drivers fear the most.
