Creve Coeur St. Paddy's Half Marathon, 10K and 5K

Lace up your running shoes and get ready to celebrate St. Paddy's Day with a festive dash at the Creve Coeur St. Paddy's Half Marathon, 10K, and 5K on Saturday, March 14, 2026, in Maryland Heights, MO. This beloved annual event, a proud part of the Missouri Runs Race Series, offers participants three exhilarating distances to choose from, catering to every level of runner and walker. Starting and finishing at the scenic Creve Coeur Lake Memorial Park, specifically from Sailboat Cove at 13725 Marine Ave., the race promises a vibrant atmosphere to kick off your St. Patrick's festivities.

The course is renowned for its picturesque setting and generally gentle terrain. Runners will traverse entirely paved trails, enjoying beautiful views around Creve Coeur Lake. While largely flat, the half marathon features some gentle undulations, including bridge crossings over the Missouri River and a brief stretch on the Katy Trail, offering a few rolling hills and a notable climb on the bridge approaches. The 10K boasts a flat and fast 6.2-mile loop, ideal for those chasing a personal best, while the 5K presents an accessible and family-friendly 3.1-mile course around the lake. Hydration is well-covered with plentiful aid stations offering both water and sports drinks, particularly for the half marathoners.

Beyond the scenic routes, the Creve Coeur St. Paddy's Run is celebrated for its festive spirit and impressive runner perks. All finishers of the half marathon will proudly receive a finisher medal, while all participants across all distances earn a commemorative finisher pint glass and a delicious shamrock cookie, perfect for post-race celebrations. Participants can also choose between a classic t-shirt or a performance thin-tec poly hoodie. The event supports a great cause, partnering with the ALS Association – St. Louis Regional Chapter. With typical race day conditions seeing highs around 57°F and lows around 37°F, and a 16% chance of precipitation, it's often perfect running weather for a memorable St. Paddy's experience.
