When we were kids we both wanted to be sporting superstars. There was just one thing standing in our way – we weren’t all that good. But we were really good at science, so we combined our love of sport with our need to know why and how, and we became sports scientists. Now we get to do experiments with sports stars to discover the secrets behind their success. We analyse games to understand the tactics of the winning team. And we even get to help athletes break world records by inventing better ways of training. But every now and then, when no one’s watching, we still pretend to be sporting superstars!
