25 years ago we published Aerobic Tennis, by Bill Wright — how to use tennis to get in shape, to have fun while working out. Instead of running and going to the gym, you use tennis to stay fit. The idea was ahead of its time, for in recent years what’s being called “Cardio Tennis’ is this very idea. We’ve just now reprinted the book; it would make a great gift for a tennis player. Bill was head tennis coach at University of California at Berkeley and later the University of Arizona. In 2006 he was elected into the Intercollegiate Coaches Hall of Fame.

I hung out with Bill for about a year while working on this book and we had some great adventures. I flew into Vail to meet him and work on the book late one summer. He picked me up at the airport and said he’d entered us both in a race the next day, which turned out to be a rough ross-country muddy 7-miler in the rain (at 9000′ elevation). And to make matters worse, he beat me! Bill’s high-energy, and it’s infectious.
