Join us for a colorful celebration on Saturday, April 4, 2026, at Bulldog Park as the community comes together for a special event celebrating the City’s 40th Anniversary. The morning kicks off with the Color Run at 7:00 a.m., followed by community activities and fitness classes at 8:00 a.m., and wraps up with the community egg hunt at 12:00 p.m.. Color Run registrations are limited and available on a first-come, first-serve basis, so don’t wait—once spots fill up, they’re gone! Groups of five or more can receive a discount by registering in person at the Rio Vista Community Center or by emailing Hello@costx.us; for more information call (915) 860-8615. Be part of the fun, bring your friends and family, and make memories as we celebrate this milestone together—and be sure to follow the City on Facebook and Instagram for updates and event announcements so you don’t miss out.
