Lace up your running shoes for the Shamrock Shuffle 5K/1 Mile on Saturday, March 21, 2026, in Patterson, MO, for a festive spring race that supports a wonderful cause. Held at the scenic Otahki Lake KOA, this event offers a welcoming atmosphere for both seasoned runners and casual participants. The course itself winds through the park on gravel paths and features moderate hills, providing an engaging challenge amidst charming scenery. The 1-mile fun run follows a continuous loop, while the 5K offers a chance to test your limits.

Typical race day conditions in late March bring pleasant temperatures, with highs around 60F and lows around 35F, and only a 16% chance of precipitation, creating ideal running weather. The event kicks off with the 1-mile run at 9:00 AM, followed by the 5K at 9:30 AM, after an 8:00 AM registration and bib pick-up at Otahki Lake Lodge. Participants are encouraged to embrace the St. Patrick's Day spirit by donning their best green attire, adding to the joyful community atmosphere. All 5K and combo participants will receive a participation medal, snacks, drinks, a sticker, and a t-shirt (guaranteed for the first 35 registrants), while 1-mile runners receive a medal, snacks, drinks, and a sticker. Awards will be given to the top three 5K finishers.

What truly sets the Shamrock Shuffle apart is its commitment to charity; all proceeds benefit the Care Camp Foundation, an organization dedicated to providing empowering outdoor experiences for children with cancer and their families. Join fellow runners for a memorable day that combines fitness, fun, and philanthropy at the picturesque Otahki Lake KOA.
