At the heart of the ranch is a 0.625 mile oval race track, 50 feet wide with fiberglass railings on both the inside and outside, engineered for drainage and raised 14 feet on the south end. Supporting the operation are 2 major training barns totaling over 26,000 SF offering 44 concrete 12 x 12 stalls, tack rooms, vet rooms, wash racks, offices, kitchens, feed & storage rooms, automatic waterers, horse walker areas, & efficiency apartments. The impressive 22,000 SF main barn features 36 concrete stalls, vet lab, therapy room, tack and feed rooms, wash racks, office suites, foreman's quarters, efficiency apartment, horse walker, round pen, & additional support facilities. Numerous additional barns provide hay & grain storage, maintenance & equipment space, shop areas, vehicle wash facilities, paddock barns, mulch bins, & shaving storage.

The property is enhanced by 10 paddocks with sheds, an observation clocking stand, multiple ponds, & over 10 miles of pipe fencing, along with chain-link fencing and numerous gates for efficient ranch management.
