About

A Merry Christmas Run 5K/10K/13.1 DENVER/AURORA is held in Centennial, Colorado, on December 26, 2026, and covers four distances from a shared 7:30 a.m. start: the half marathon (13.1 miles), the 10K, the 5K and a one-mile family fun run. Waves go off at set times, runners and walkers are both catered for, and every entrant receives a race shirt, a finisher medal and a digital training kit delivered to their home.

Racing on the Front Range means racing at altitude, and the practical effect is simple: expect to be slower than at sea level over any of these distances, and pace by effort instead of by your usual splits. Visitors are better off treating the half as a long steady run than as a time trial. Locals have no such excuse, and twelve weeks with a weekly long run will have you ready for 13.1 miles. The one-mile run is the easiest way to bring family who do not race.
