Lace up your running shoes and embrace the festive spirit at the Creve Coeur St. Paddy's Half Marathon, 10K & 5K Run/Walk on Saturday, March 14, 2026, in Maryland Heights, MO! This vibrant event, celebrating its 10th year, invites runners and walkers of all levels to enjoy a scenic tour through Creve Coeur Park. Participants can choose from a challenging Half Marathon (13.1M), a spirited 10K, a fun 5K, or even a 100M Kids Dash, ensuring a distance for everyone.

The course, praised by runners as smooth and easy, unfolds entirely on paved trails, offering picturesque views of Creve Coeur Lake and its surrounding nature.

Aid stations are plentiful along the route, providing water and sports drinks to keep you hydrated. Typical race day conditions in mid-March offer pleasant temperatures, with highs around 57°F and lows around 37°F, and a relatively low 16% chance of precipitation.

Beyond the race itself, this event fosters a strong community atmosphere with a festive St. Patrick's Day celebration. All finishers receive a commemorative pint glass, Half Marathoners earn a finisher medal, and a shamrock cookie awaits at the finish line. The race proudly supports the ALS Association – St. Louis Regional Chapter, adding a meaningful cause to your memorable run. The start and finish are conveniently located at Sailboat Cove within Creve Coeur Park, with shuttle services available from Grace Church to ensure a smooth arrival.
