'There will be racing opportunities for all categories-New Mexico breds and Open horses, wide ranges of allowance classes and plenty of spots for different claiming levels-and the purses will be unlike anything seen in this region of the country. 'With the realignment of the 2023 New Mexico racing calendar this is a tremendous opportunity to showcase New Mexico horse racing,' said Christopher McErlean, Vice President of Racing for PENN Entertainment, parent company of Zia Park.
