Tomas Berdych

I do a lot of biking. I need that mileage and the long-distance stuff because tennis demands it. My fitness trainer is always trying to convince me to do an Ironman. I can probably run the marathon, I can make the 112 miles on the bike, but I will never swim for 2.4 miles. I will die after 100 meters.

It's always hard to find the best friends in the locker room because we are all competing against each other - but the real friends you are going to definitely find off the court because we are competitors in between.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.
