The installation of Polytrack in 2005 began with the complete removal of the old dirt surface.

The foundation of Polytrack: perforated drainpipes that circle the track.

Turfway's upgrades include a Rider Safety System rail. Also visible, the second of two layers of stone.

A surprising Polytrack component: a layer of porous macadam.

Trucks dump the first Polytrack surface material onto the track. This final, visible portion of the Polytrack surface is comprised of polypropylene fibers, recycled rubber, and silica sand, all coated with wax.

You won't see this at Turfway. Polytrack is never muddy, always fast.

Martin Collins, the inventor of Polytrack, also invented the Gallop-Master to maintain it.

Regal Reproach won North America's first race on Polytrack on September 7 at Turfway Park.
