The test has gone very well over the last few days. We have completed a lot of laps, mostly focusing on tyre testing, but also doing reliability work and finding a good set-up around the Bahrain circuit before the first race.

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.

I always think I should try to get to bed early, but then I can't stop myself from watching telly and fiddling around on the net.

A lot of people think Formula One isn't a sport because everyone drives a car when they go to work in the morning. But we're pulling up to six G on a corner or during breaking, which is almost like being a fighter pilot. So we have to do a lot of work on our neck muscles.

I think social networks are really working for the drivers, because we're able to talk directly to fans and they get first-hand information. And I think it's great for the partners as well and the businesses that are involved in Formula One.

I can't eat whatever I want, definitely not. I'm always controlled because I do a lot of fitness and triathlons, not just Formula One, so I always make sure I eat the right things.
