Freakin Freezin 5K - Denver

The Freakin Freezin 5K - Denver takes place in Denver, Colorado, on January 24, 2027, with a single 5K starting at 9 a.m. One distance, one start time, late January: it is the kind of race that exists to give winter training a point on the calendar.

Denver adds a wrinkle no coastal 5K has, since running at altitude costs you time even over three miles, and visitors arriving from lower elevation should adjust their expectations rather than their effort. Locals will simply race it. Either way, preparation is short: a month of three or four runs a week, one of them with faster segments, is enough for the distance. The 9 a.m. start is late enough for the coldest part of the morning to have passed, but warm up in layers you can hand off before the gun.
