Ralston Creek Half Marathon & 5k

Sunday Feb 5th



Winter Race Series Race #3


The Ralston Creek Half Marathon and 5K returns in 2017, after sold out fields in the half for the past 5 years! Join us at Colorado’s Premier Winter Half Marathon, and the finale to the 2016-2017 Racing Underground winter running series.

The Ralston Creek races feature a fun winter half-marathon and 5K run conveniently located on the west side of the Denver Metro Area in Arvada, Colorado. The courses covers a scenic mix of road and bike path over rolling terrain, and an optional early start time for half-marathon runners who expect to take more than 2.5 hours to complete the course!
