I think fans of the sport have a good understanding now of how fit Formula One drivers need to be.

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 have made lots of mistakes in terms of contracts and spending money when I shouldn't have spent money.

My 'Movember' moustache was never going to be as big as Nigel Mansell's, but I tried my best. The amazing thing is that when you try to grow a moustache, you notice everyone else's. There are some amazing moustaches on the grid.

My time at Honda was amazing. Some of my best times in Formula One, actually. I might not have won races, just one race, but I had a lot of fun.

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