The Ralston Creek Half Marathon and 5K returns in 2018, after sold out fields in the half for the past 6 years! Join us at Colorado's Premier Winter Half Marathon, and the finale to the 2017-2018 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!
HALF-MARATHON COURSE:The Ralston Creek Half Marathon course follows a mix of roads and bike paths on the west side of Arvada. The opening 5 miles are fairly flat, with a barely noticeable gradual gain in elevation. Miles 5 through 6.5 are rolling, with one good climb leading to the high-point of the course atop Ralston Mesa at 7.75 miles. From there, the course is almost all downhill and flat to the finish, with the exception of a small bump around mile 9 and a very gradual uphill in the last half-mile.

Half-Marathon aid stations are located approximately every two miles throughout the course (approximate locations are: 2.25, 4.25, 5.75, 7.25, 9.5, 11.5) All aid stations will have both water and Gatorade Endurance energy drink. Hammer Gel will be available at miles 4.25 and 9.5.
5K COURSE:The Ralston Creek 5K Run course follows a mix of roads and bike paths on the west side of Arvada. The route starts with a slight downhill in the opening mile, a flat second mile, and a very gradual uphill in the final mile. A single aid station will be located at approximately halfway into the 5K run. Click Here for a 5K Course Map
The Ralston Creek Half Marathon and 5K will offer a three wave start. Wave-1 will start at 9:00am for half-marathon runners who plan to take longer than 2.5 hours to complete the course. Wave-2 will start at 9:45am for half-marathon runners who plan to take less than 2.5 hours to complete the course. Wave-3 will start at 10:00am for all 5K runners.
This start procedure is designed to improve the finish line and post-race experience for the slower runners. The 45 minute gap in start times will allow the wave-1 runners time to spread out on the course before the faster runners begin. This start procedure is a runner favorite! Please be aware: runners starting in wave-1 who finish the race faster than 2:15 will be removed from the results and disqualified. Wave starts are timed so returning wave-1 runners and outbound wave-2 runners do not have to share the path. Please select the appropriate wave for your ability level. If you are not sure, please select wave-2.
A 2:30 half marathon time is roughly an 11-minute and 30 seconds per mile pace.
7:30 a.m. - Packet Pick-Up Opens
9:00 a.m. - Wave-1 Start (half-marathon runners expecting to take more than 2.5 hours)

Half-Marathon Age-Group Awards will be based on NET TIME, and will be presented in several ceremonies, on a rolling basis after 11:30 as award categories fill. You may also opt to skip the awards presentation, and simply stop by the awards tent to pick up your age group award if awards for your category have been confirmed. The awards tent will receive updated awards lists throughout the morning.
Raffle prizes will be presented at the finish line to random finishers. It is winter, after all! We're not going to ask you to wait around to see if you won something!
*Awards for overall top-3 will be determined by GUN TIME for both the 5K and the half marathon. Age Group awards for both races will be based on NET TIME. The scheduled time for the awards presentation may be moved a bit depending on weather and number of athletes still on course
