A Merry Christmas Run 5K/10K/13.1 DALLAS FORT WORTH

A Merry Christmas Run 5K/10K/13.1 DALLAS FORT WORTH is run in Fort Worth, Texas, on December 26, 2026. All four distances start at 7:30 a.m.: the half marathon (13.1 miles), the 10K, the 5K and a family one-mile fun run. The event puts community and camaraderie ahead of competition, and timing is optional, so you can record the run with your own app or leave the clock out of it. A race shirt, a finisher medal and a gift bag come with entry.

Optional timing changes what the race is for. Without an official clock, the half becomes a supported long run with company rather than a performance test, which suits anyone building toward a spring marathon. For that purpose, run it at the effort you would hold on a Sunday, around a minute per mile slower than half-marathon race pace. If you want a hard effort instead, the 5K is short enough to race by feel and still be worth something the next day.
