Ralston Creek Half Marathon & 5k
An event every year that begins at 12:00am on day first of February, repeating until February 2, 2025
The Ralston Creek Half Marathon and 5K returns in 2019, after sold out fields in the half for the past 7 years! Join us at Colorado’s Premier Winter Half Marathon, and the finale to the 2018-2019 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!
