Unicorn 5k (Denver-East)

Unicorn 5k (Denver-East) is held in Denver, Colorado, on April 25, 2027. A single format is on the schedule, a 5K (3.1 miles), starting at 9:30 a.m. on the east side of the city.

One thing to plan for if you are traveling in: Denver sits a mile above sea level, and at that altitude a hard 3.1 miles feels noticeably harder than the same effort at home. Either arrive the day before and race by feel rather than by watch, or give yourself a couple of weeks to adjust. Runners based locally have no such problem and can treat this as a straightforward spring benchmark, with three or four weeks of sharpening, one weekly session of 400 or 800-meter repeats, and an easy few days beforehand. The 9:30 a.m. start leaves plenty of time for a full warm-up.
