The Ralston Creek Half Marathon and 5K returns in 2015, after sold out fields in the half for the past 3 years! Join us at Colorado's Premier Winter Half Marathon, and the finale to the 2014-2015 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 a separate early start time for half-marathon runners who expect to take more than 2.5 hours to complete the course! Your entry includes a Ralston Creek long sleeve half zip technical running shirt if registered by 11:59pm on January 20th (short sleeve tech-T after January 20th), finisher's medal for all half-marathon finishers, great post-race food, participant goody bag, entry into the post-race drawing for some cool sponsor gear, and for those up front, a shot at some of the $1,000 half-marathon prize purse!!! We hope to see you on February 8th.
