Everyone can do simple things to make a difference, and every little bit really does count.

I run a lot. If I don't have time to go to the gym or don't have time to work out properly, I will go for a quick run. I think running is a great way to stay fit, and I really concentrate on fitting into a realistic urban lifestyle.

We always had our own vegetables growing up and now I'm doing it with my kids at our house in the country.

We try to make earth-friendly decisions whenever we can, as it's part of our brand DNA.

The main challenge is technology and that's something I really push and work closely with Adidas on. They're real leaders in sports performance; always trying to push that further and further and get the best technology they can. That takes time and has rigorous testing, it's very laborious, but it's also very rewarding. You get to work with fantastic athletes, and that's a fantastic thing that has nothing to do with my day job in ready-to-wear.

I never wanted to make it too easy for people to sum me up.

At times I make music, but in private.
