Believe! 5K & 1 Mile Fun Run

Believe! 5K & 1 Mile Fun Run takes place in McKinney, in Collin County, Texas, on Saturday, November 28, 2026. The morning opens with the Believe! Santa Chase at 8:00 a.m., followed by the 1-mile fun run at 8:05 a.m. and the 5K at 8:30 a.m. The event benefits Holy Family School and the Alliance of Elite Youth Leadership (AEYL), and its scenic course runs through McKinney's historic downtown on a route designed for walkers as well as runners.

The race marks the festive start of the holiday season in McKinney, and once you cross the finish line you can stay for the town's Home for the Holidays celebration, with food and holiday entertainment. As a road 5K on downtown streets, it is well suited to first-timers and families, while the 1-mile gives kids and casual walkers a shorter option. A few weeks of easy running, two or three times a week, is plenty of preparation for the 5K, and the flat-to-rolling character of a downtown course lets you focus on enjoying the morning rather than managing a tough route.
