Oklahoma Challenge Championship tops three-stakes program

Remington Park will put on a trio of stakes for Quarter Horses on Sunday, with the main event the Grade 2, $100,000 Oklahoma Challenge Championship.

A field of 10 older horses has been entered in the 440-yard race. The group includes Rockin Disco, the defending champ, and Exquisite Stride, who in 2014 ran sixth as the favorite in the prestigious All American Futurity at Ruidoso.

Remington also puts on the Grade 3 Distaff Challenge for fillies and mares and the Grade 3 Distance Challenge.
