Free First Timer Clinic

Is your child excited to try the event for the first time? Make sure they're prepared with a free first-timer clinic on Sunday, September 4, at Butterfield Crossing Park. The clinic will be at 1:00 PM for ages 7-18 and 1:45 PM for ages 5-6.

The clinic is designed to ease the anxiety of kids and their parents, who are both encouraged to attend. The class will include a review of the racecourse. To ensure individualized attention, clinic space is limited, and registration is required. Registration ends Friday, September 2.
