About the Running Scared 5K/13K - Denver
The course runs along the Platte River Trail and stays flat the whole way. There are no real hills to speak of, and the trail surface makes it a good option if you are chasing a personal best. Spectators can get eyes on runners easily, and the out-and-back nature of trail courses means familiar faces appear more than once.
Check-in opens on race morning, with enough time before the first wave to pick up your bib without rushing. Self-serve water stations are spaced out along the course, so if you plan to run hard and skip stops, carrying your own water is worth considering.
