Scientific Study on Speed, Pace and Aerodynamic Drafting in Thoroughbred Horse Racing

“Choice of pacing strategy and the benefit of aerodynamic drafting are thought to be key determinants of racing performance. These effects have largely been analyzed without reference to final outcome, in small datasets with low temporal resolution, and a focus on human swimming, cycling and running. Here, we determined the position and speed of 44,803 racehorses, once per second, in 3,357 races ranging in length from 1006 to 4225 m (50.9–292.9 seconds duration) using a validated radio tracking system.

We find that aerodynamic drafting has a marked effect on horse performance, and hence racing outcome…”
