MLK Jr. Freedom Run 5K/10K/13.1 DENVER/AURORA

MLK Jr. Freedom Run 5K/10K/13.1 DENVER/AURORA is based in Centennial, Colorado, on January 16, 2027, one of the national dates marking the legacy of Dr. Martin Luther King Jr. The half marathon (13.1 miles), the 10K, the 5K and a one mile family fun run all begin at 7:30 a.m. No timing chips are used. Entry includes a bib, a shirt, a finisher towel and a medal, and there is a virtual option for anyone who prefers to run from home.

Running at Denver area altitude is worth planning for if you are visiting: expect to be slower than at sea level for the same effort, and judge the day by feel rather than by the numbers on your watch. Locals face the reverse problem and can use the half as a solid aerobic session. Either way, twelve weeks of consistent running with a weekly long run is the usual preparation for 13.1, and the shorter options are there if your winter has been patchy.
