This episode studies the thoroughbred racehorse, an animal biologically engineered for speed. They dissect an elite racehorse to reveal the extraordinary spring system that propels it to 45mph, its super-sized organs and built-in turbo-booster. Simon Watt visits the top breeding centre in Europe to find out how to produce a champion; and Mark Evans investigates the science behind their phenomenal performance and their vulnerability to injury.
