This month we look back at the history of synthetic equestrian surfaces. To do this we first have to consider a definition of a synthetic surface. It is generally considered that any surface that is man-made, and that does not include simple dirt, can be termed a synthetic surface. A tighter definition sometimes used is a man-made surface that does not rely on water/moisture to hold it together, so essentially constitutes all coated surfaces. This definition would therefore preclude all uncoated surfaces. We'll stick with this narrow one for now.
