The Shamrock Shuffle 5K in San Antonio, Texas, on Saturday, March 14, 2026, invites runners of all levels to kick off their St. Patrick's Day celebrations with a festive and energetic race experience. This 12th annual event, featuring both a 5K and a 1K Kid's Run, has become a cherished tradition, known for its vibrant community atmosphere and abundance of green.

The scenic and fast course at Lady Bird Johnson Park offers a relatively flat, out-and-back route along shady paved park trails, making it ideal for those chasing a personal best or enjoying a leisurely shuffle. While mostly flat, the course does include a couple of gentle inclines, presenting a manageable challenge. Runners can expect typical race day conditions with pleasant highs around 76°F and lows around 55°F, and only a 7% chance of precipitation. The race is also jogger, stroller, and dog-friendly (with a request for dog-runners to start at the back), ensuring everyone can partake in the fun.

Beyond the run, the Shamrock Shuffle delivers a high-energy post-race party complete with music, festive costumes, and celebratory green beer. Participants receive finisher's medals and commemorative shirts, while awards for top finishers are real shamrocks. More than just a race, this event also proudly supports Transplants for Children, with a portion of the proceeds dedicated to their cause. The 5K starts at 8:30 AM CDT, preceded by the 1K Kid's Run at 8:00 AM CDT, all contributing to an unforgettable St. Paddy's Day weekend tradition.
