Ralston Creek Half Marathon
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!
The race also serves as the second event in our three-race Winter Running Series which takes place in three communities just a short drive west of Denver!!!
